Manufacturing advanced electronics requires understanding millions of signals generated across complex assembly processes. Instrumental builds systems that capture and analyze those signals — images, test results, and process data — enabling engineers to discover failures, identify root causes, and deploy production controls that improve yield and product maturity. Leading companies such as NVIDIA, Cisco, and Meta rely on Instrumental to accelerate new product development and scale manufacturing across global factories. Instrumental has become mission-critical for manufacturers building and scaling the next generation of AI infrastructure hardware.
Instrumental is hiring a Senior Platform Engineer who will take broad ownership of our platform layer: the services, pipelines, and infrastructure that the rest of engineering depends on. The ideal candidate will be able to operate independently on ambiguous problems, make sound architectural decisions with limited guidance, and raise the bar for the team through both their technical contributions and their influence on engineering practices. We are explicitly looking for someone who has already demonstrated sustained impact in a professional setting, ideally at a startup where they owned systems end-to-end.
What You’ll Be Doing:

• Own the full software development lifecycle across design, implementation, testing, deployment, and operations
• Build and evolve core platform services with an emphasis on pragmatism, maintainability, and operational excellence
• Improve system simplicity, reliability, security, observability, incident detection, and response
• Leverage AI-assisted development tools to improve engineering productivity and iteration speed
• Identify, evaluate, and prioritize new tools, technologies, and technical debt based on ROI
• Collaborate across engineering teams to ensure platform capabilities meet product, AI, and edge system needs

We’re Looking for Someone Who:

• Has 5+ years of backend or platform engineering experience; startup experience required
• Takes full ownership of production systems — from design through deployment and operations
• Makes pragmatic, well-reasoned technical decisions and can articulate their tradeoffs
• Is fluent in Python or Go; experience with other backend languages is a plus
• Has experience with data modeling and data processing pipelines
• Leads the way in AI tool adoption on their teams to improve development productivity and outcomes
• Communicates clearly and collaborates effectively across teams

We’re a growing team that works collaboratively, supports each other, and is energized by having an impact. We value passion and the ability to learn — you’re encouraged to apply even if your experience doesn’t match the job description precisely!
