About Positron AI
Positron AI is building next-generation AI inference accelerators designed from the ground up for low-latency, high-throughput large language model inference. Chips built for the training era keep running into two walls at inference time: memory bandwidth and chip-to-chip networking. We designed our architecture to break through both. Our first-generation Atlas systems are already in production on Oracle Cloud Infrastructure. Asimov, our first custom ASIC, takes that architecture to silicon. In simulations, Asimov delivers several times more tokens per dollar and tokens per watt than leading GPUs, at a fraction of the power. Paired in our Titan system, Asimov is built to serve models beyond 16 trillion parameters. In September 2026, we raised $875 million at a $5 billion valuation. NEA led the round, joined by Atreides Management, Valor Equity Partners, and others, to bring Asimov and Titan to market. Our team includes engineers from Groq, Lambda, NVIDIA, Meta, F5, and many other industry leaders.
As a Senior Software Engineer on our Manufacturing Test team, you will build the reliable test software that verifies the quality of Positron hardware, catches defects before systems ship, and produces diagnostics that engineers can act on. You will own tests from initial development through production deployment, partnering closely with hardware, firmware, and manufacturing teams to improve test coverage, repeatability, and failure isolation. This is a hands-on senior role for an engineer who writes production Go, understands systems down to the hardware, and uses agentic coding tools to move fast without compromising rigor.
This role is based in-office at our Spokane Valley, WA location. Candidates must be able to work on-site as required.

Agentic Development
While this role is currently posted at a specific level, we are a growth-oriented organization and are open to hiring at a more senior level for the right candidate. Please note that this job description serves as a focused but generalized overview of the role; specific responsibilities and impact expectations will be tailored to the experience and seniority of the final hire.
Success in this role means delivering production-ready hardware tests in Go that carry clearly defined pass/fail criteria, actionable diagnostics, automated regression coverage, and solid documentation, with their effectiveness proven against both known-good hardware and representative failures. It also means using agentic coding to accelerate implementation, debugging, and test development while remaining fully accountable for design, correctness, review, and hardware validation.
The base salary range for this role is $200,000 – $250,000.
Please note that the figures provided represent the base salary range only and do not include other elements of our total compensation package, equity, or comprehensive benefits.
At Positron AI, we value the unique expertise each candidate brings. While the range above reflects our typical expectation for the position, we reserve the flexibility to exceed this range for candidates whose specialized skills, significant experience, or unique qualifications fall outside the standard scope of the role. Final offers are determined based on a variety of factors, including internal equity, and individual impact.
We want you to do your best work and feel confident that you and your family are taken care of. That means comprehensive coverage, real time to rest, and support for your future.
