Ann Arbor Tech Internships

Interning in Ann Arbor is the single most reliable path into a full-time engineering offer at a named local employer. Every flagship tech company in town runs an intern program, and at most of them the return-offer rate for strong performers sits north of 70%. The catch is timing. The best Ann Arbor internships open applications in August and September for the following summer, and the ones that matter most are usually closed by early November. By the time the late-winter career fair happens, you are interviewing for leftovers.

This guide walks through who hires, when to apply, what you will get paid, and which teams convert interns into full-time engineers at the highest rate. It is written for U-M CSE and Ross students first, then Michigan State, Purdue, Illinois, Wisconsin, Ohio State, and other Big Ten engineering students who want to intern in Michigan. The moving to Ann Arbor for tech guide covers housing logistics for out-of-town interns, and the tech jobs in Ann Arbor guide tracks which teams are actively hiring full-time engineers, which is the best leading indicator of where the intern spots will open.

The Ann Arbor intern calendar

Most students miss the fact that Ann Arbor's intern timing does not look like the Bay Area's. Here is the actual rhythm.

Mid-August through early October. Fall applications open at the big enterprise employers. Google Ann Arbor, KLA, Cisco Duo, Toyota Research Institute, and Amazon all post summer intern requisitions in this window. For sophomore and junior standing, this is the most important 60-day stretch of your year.

Mid-September. The U-M CSE Career Fair runs mid-September on North Campus, split between the EECS Atrium at the Bob and Betty Beyster Building and the Duderstadt Center. For 2026 it is scheduled September 16 and 17. Most Ann Arbor employers that hire interns staff a booth, and a non-trivial number extend interviews inside the following week. Go on the first day. The best recruiters are saturated by 2 p.m. on day two.

Mid-November. MHacks, the U-M collegiate hackathon co-founded in 2013 and run by MHacks organizers under the Michigan Hackers umbrella, happens on North Campus over a weekend. Censys, Voxel51, Duo, and most AA startups send engineers as mentors and recruiters. Intern offers have been extended on the floor. For 2026, MHacks is tentatively November 14 to 16 at the Ford Robotics Building and the Duderstadt.

January through March. Late-cycle postings. This is when smaller Ann Arbor startups (Blumira, Plinqit, Nutshell, Optilogic, Workit Health) typically open their summer intern roles. If you missed the fall window, this is your second bite. Do not wait for an April career fair.

Summer (May through August). Internship itself. Standard length is 10 to 12 weeks. Most programs run a single cohort; Toyota Research Institute and Google AA run overlapping cohorts.

The flagship employer list

Google Ann Arbor

Google's 2300 Traverwood Drive campus is a 135,000 sq ft facility with roughly 400 Googlers, most on the Ads engineering, support, and internal IT sides. The Ann Arbor office hosts both STEP interns (sophomore-focused) and standard SWE interns (junior and senior). STEP is the single best first-internship program available to U-M students: 12 weeks, structured mentorship, real production code, high conversion to the following summer's SWE intern role. Applications open in August. Pay runs roughly $11,200 per month for SWE intern and $8,400 per month for STEP as of 2026 public data, with housing stipend and subsidized meals on-site. Return offer rate for strong SWE interns at AA has historically sat in the 75 to 85% band. Apply through google.com/about/careers.

Cisco Duo

Duo Security, the $2.35B Ann Arbor exit now inside Cisco, is the single largest cybersecurity intern employer downtown. Their office in the Liberty Square building runs a summer intern cohort of 20 to 40 students across engineering, security research, product, and design. Stack is Java, Kotlin, Go, and Python. Interns are embedded on real teams and ship code to production by week 4. Stipends run roughly $8,000 to $9,500 per month. Return offer rate has been strong; multiple cohorts have reported 80%-plus conversion among engineering interns. Apply at jobs.cisco.com filtered to Ann Arbor, typically open in late August. Ask to be routed to a Duo-branded team rather than a general Cisco one if security is your interest.

Censys

Censys, the internet intelligence company spun out of U-M's ZMap research at 116 South Main Street, hires a smaller but high-signal intern class. Ten to fifteen engineering interns per summer is typical. The work is Go, Rust, and large-scale data engineering on an internet-scanning platform used by the Office of the Director of National Intelligence under a multi-year contract announced in late 2024. Stipend sits around $8,500 per month. The team runs weekly engineering-wide demos and the bar for interns to present is the same as full-time. Return offer rate has been among the highest in town for U-M interns specifically. Applications open in September. Apply at censys.com/careers.

KLA Ann Arbor

KLA opened its second US headquarters on the North Campus Research Complex-adjacent campus in November 2021. The 600-engineer AI R&D and semiconductor process control operation hires 40-plus interns per summer across software engineering, image processing, ML, and applied physics. KLA's intern pipeline runs through a structured internship program with formal technical-track mentors and a final project presentation. Stipends range from $7,500 to $9,000 per month depending on level. Return offer rate is high for interns matched well to their team. The image-processing and AI groups are the densest concentrations of U-M CSE alumni outside of Google. Apply at kla.com/careers. The fall window opens in August.

May Mobility

May Mobility is the largest pure-play autonomous vehicle employer in Ann Arbor, 342 employees, co-founded by U-M robotics professor Edwin Olson. The intern program is smaller, roughly 15 to 25 engineering interns across perception, motion planning, localization, simulation, safety supervision, and vehicle systems. Stack is C++, Python, ROS, and increasingly Rust on the middleware layer. Stipends run $7,500 to $9,500 per month. The team hires heavily from U-M Robotics master's and PhD programs; undergraduate interns skew junior and senior with strong ROS or autonomy coursework. Apply at maymobility.com/careers. Applications open in September.

Toyota Research Institute Ann Arbor

TRI Ann Arbor, TRI's third U.S. facility, sited near the U-M campus, focuses on autonomous driving, robotics, AI, and materials science. The team runs a competitive research intern program that pairs a small cohort with TRI research scientists, often on published-paper trajectories. Stipends run $8,000 to $10,000 per month depending on year in program. Many interns return as full-time research engineers. This is the most research-flavored internship on the Ann Arbor list and the best fit for PhD-track students. Apply at tri.global/careers.

Toyota Motor North America R&D

Toyota Motor North America R&D is a separate entity from TRI and runs out of the York Township and Ann Arbor technical center campus, roughly 760 employees with a 50-year history in the region. Their intern program leans toward vehicle engineering, embedded, controls, and applied ML for next-generation vehicles. Stipends sit around $7,000 to $8,500 per month. The culture is more traditional OEM than the TRI research cohort; interns do real engineering with longer-term project horizons. Apply at amrd.toyota.com/careers.

Voxel51

Voxel51, the computer vision dataset platform funded by a $30M Bessemer-led Series B in May 2024, runs a small but high-impact intern program. Five to ten engineering interns, all Python and ML focused, all shipping to the FiftyOne open-source codebase or the enterprise tier. The open-source contribution aspect gives interns portfolio work they can publish. Stipends run $7,500 to $9,000 per month. Apply at voxel51.com/careers.

Blumira

Blumira is the cloud SIEM and XDR company funded by Ten Eleven Ventures in a 2023 Series B with Jonathan Oberheide of Duo participating. Their intern cohort is small, usually five or fewer, focused on detection engineering and platform work. Stack is Go and Python. Stipends are competitive with the mid-tier startup band, $6,500 to $8,000 per month. Return offer rate is high given the small cohort.

Barracuda, Menlo, Amazon Robotics, and Torc

Barracuda Networks maintains a 45,000 sq ft R&D office at the old Borders HQ on Maynard Street. Intern hiring is steady but smaller than Duo's: 8 to 15 per summer in email, network, and application security. Stack is C++, Python, and cloud-native. Menlo Innovations at 410 N. Fourth Ave hires a small number of interns to pair-program alongside full-time Menlonians at a single machine. Amazon Robotics maintains engineering offices in Ann Arbor tied to the broader robotics corridor; intern hiring is limited but real, standard Amazon stipend around $9,500 per month with relocation and housing. Torc Robotics, the Daimler Truck subsidiary, opened its 32,000 sq ft Ann Arbor Technology Center in June 2025; 2026 is its first full intern year with roles in perception, sensor fusion, and safety supervision.

Typical stipends by tier

Ann Arbor intern compensation clusters into four bands in 2026.

Tier 1, FAANG and top-funded AV and AI: $9,000 to $11,200 per month. Google AA SWE, Amazon Robotics, May Mobility senior-year interns, TRI research interns.

Tier 2, flagship security and enterprise: $8,000 to $9,500 per month. Cisco Duo, Censys, KLA, Voxel51.

Tier 3, mid-stage startups: $6,500 to $8,000 per month. Blumira, Workit Health, Nutshell, Genomenon, Barracuda.

Tier 4, seed and early-stage startups: $5,000 to $6,500 per month. Small SPARK-portfolio startups, some of which offer equity in lieu of higher cash. Accept these for the learning, not the stipend.

Housing for out-of-town interns is typically not provided outside of Google, Amazon, and the largest programs. Plan on $1,200 to $1,800 per month for a summer sublet in Kerrytown, Burns Park, or the North Campus residential area. See the Ann Arbor neighborhoods for tech workers guide for where to sublease.

Which programs actually convert to full-time offers

Return-offer rate is the number to optimize for, because an intern offer at a company that extends 80% return offers is roughly the same as a full-time offer deferred by one year. The highest-signal conversion programs in Ann Arbor as of recent cohorts:

Google AA SWE intern: 75 to 85% return offer rate for strong performers.
Cisco Duo engineering intern: 80%-plus return offer rate in recent cohorts.
Censys engineering intern: consistently high, driven by small cohort size and tight mentor ratios.
KLA AI R&D intern: strong, particularly for interns matched well to their team from day one.
May Mobility engineering intern: high for PhD-track robotics interns, more variable for undergrads.
Voxel51 intern: high given cohort size.

The programs with the lowest conversion are usually the largest cohorts at companies with hiring freezes. Ask about current full-time hiring plans during the intern interview. A recruiter who dodges the question is telling you something.

U-M specific resources

The U-M CSE Career Center at the Bob and Betty Beyster Building (2260 Hayward St) hosts the CSE Career Fair, runs employer info sessions throughout fall and winter terms, and maintains the Handshake-integrated job board. EECS students have first access to CSE-branded info sessions; non-EECS students in LSA CS or the Data Science major should register through Handshake. TechArb, the U-M student venture accelerator at the Center for Entrepreneurship, is worth knowing even if you are not founding a startup; its alumni network recruits interns directly (SkySpecs most prominently). Michigan AI, the U-M AI research group, runs open seminars that double as recruiting funnels for Voxel51, Censys, and TRI.

How to position yourself

Three moves matter more than the others. First, contribute to at least one open-source project in a stack a named AA employer uses: Voxel51's FiftyOne, Censys-adjacent ZMap work, or any ROS repo for robotics. Second, show up to Ann Arbor tech meetups and talk to engineers before you apply; a2NewTech on the third Tuesday is the highest-signal monthly gathering. Third, apply early in the cycle. The August through October window is when the best spots close.

If you are a U-M CSE junior with a 3.4-plus GPA, one open-source contribution, and one project with real users, you should expect at least one Tier 1 or Tier 2 offer in a typical year. The Ann Arbor software engineer salary report has the full-time comp bands you will negotiate against when you convert.
