Senior Software Engineer, Manufacturing Test

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.

Role Overview

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.

Key Responsibilities

Test Development in Go

• Design, build, and maintain production-quality manufacturing tests in Go with clearly defined pass/fail criteria, actionable diagnostics, and thorough documentation.
• Develop hardware tests and diagnostics across PCIe/AER, CPU, memory, I²C, SPI, PRBS, NICs, BMC/IPMI/Redfish, and drive I/O.
• Build system-level functional, stress, reliability, and performance tests for Positron platforms.

Test Strategy and Validation

• Translate platform requirements and failure modes into prioritized coverage plans with measurable pass/fail criteria, balancing defect detection, runtime, and repeatability.
• Validate test effectiveness against known-good hardware and representative failures, and maintain automated regression coverage as tests evolve.

Failure Analysis and Cross-Functional Partnership

• Investigate ambiguous failures and isolate root causes across hardware, firmware, and operating system boundaries.
• Partner with hardware, firmware, and manufacturing teams to close coverage gaps, and clearly communicate risks and tradeoffs across teams.

Agentic Development

• Direct coding agents through well-scoped tasks to accelerate implementation, debugging, and test development, while retaining full accountability for design, correctness, code review, and hardware validation.

Required Qualifications

• 5+ years demonstrated experience designing, shipping, debugging, and maintaining production-quality Go software, including concurrency, error handling, automated testing, and maintainable interfaces.
• Experience with FPGA, AI, Inference HW test.
• A strong understanding of computer architecture, including CPUs, memory, PCIe, storage, networking, and the interactions among hardware, firmware, and operating systems.
• Hands-on experience writing hardware tests and isolating failures across multiple domains such as PCIe/AER, CPU, I²C, SPI, memory, PRBS, NICs, BMC/IPMI/Redfish, and drive I/O.
• Proven ability to turn platform requirements and failure modes into prioritized coverage, measurable pass/fail criteria, and validation plans.
• Practical skill directing coding agents through well-scoped tasks, providing relevant context, critically reviewing generated changes, and verifying behavior through software tests and hardware validation.
• Senior-level engineering ownership, with the ability to independently drive test development and technical decisions and to communicate coverage gaps and tradeoffs across teams.
• Bachelor’s in Computer Science, Electrical Engineering, Computer Engineering, or similar equivalent additional years of experience

Preferred Qualifications

• A track record of delivering and supporting hardware tests at contract manufacturers, including deployment, station qualification, documentation, and remote troubleshooting.
• Familiarity with analyzing manufacturing test data to improve coverage, reduce false failures, and shorten debugging time.
• Experience building CI/CD pipelines, automated regression infrastructure, and test release management processes.

Leveling & Scope

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.

What Success Looks Like

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.

Why Join Us?

• Own the test software that stands between a new class of AI inference hardware and production, with direct influence on the quality of every system Positron ships.
• Work across the full stack, from PCIe and BMC to system-level stress testing, alongside hardware, firmware, and manufacturing engineers bringing Asimov and Titan to market.
