Java Developer, Software Engineer
We're growing the technology group at Best Buy and need a mid-level Performance Engineer who treats reliability as a feature, not an afterthought. This is $74,000 - $112,000 for 4 years of People Management, an internship schedule, and a mid-level stake in where Best Buy heads next.
Key Responsibilities- Pair gRPC and Java in a pipeline Best Buy can extend without your help later
- Break large technology initiatives into Java increments Mankato can actually deliver
- Design gRPC APIs other Mankato, MN teams will still thank you for next year
- Ship the data-driven Agile features that move Best Buy's technology roadmap forward
- Identify bottlenecks and propose architectural improvements proactively
- Spike an Agile proof of concept fast when Best Buy needs a yes-or-no answer
- Catch the Java race conditions that only surface under Mankato peak traffic
- Wrangle Swift config across environments so Mankato staging mirrors production
- Ability to learn new technology systems quickly and apply them effectively
- Familiarity with Best Buy-scale workflows, or the appetite to reach them
- Prior experience working on-site in Mankato, MN, or willingness to relocate
- The grit to debug at 4pm on a Friday without complaint
- The kind of empathy that makes hard feedback land softly
Every product at Best Buy reflects the mission-soaked standards our Mankato, MN team holds itself to. We build psychological safety the boring way: by actually following through on what we say.
You get $74,000 - $112,000, a robust benefits suite, and hands-on mentorship aimed at making you a stronger technology professional.
Still warm and still open, this internship listing just got updated.
