Hardware Test Infrastructure Engineer

About this role

Efficient is hiring a Hardware Test Infrastructure Engineer to build and scale ATLAS, a critical testing and benchmarking platform for ultra-low-power processors. This full-stack role bridges embedded systems and cloud infrastructure, requiring expertise in Go services, Kubernetes, C/C++ test programs, and hands-on work with diverse embedded hardware platforms.

What you'll do

• Deploy, maintain, and troubleshoot embedded hardware platforms (FPGA, Ambiq Apollo, PIC32, Efficient E1)
• Develop low-level C/C++ test programs to measure performance, power, and functionality across hardware targets
• Design and maintain Go-based server/client applications with PostgreSQL and Redis for operations
• Build Python automation tooling and scripts for workflow orchestration, result parsing, and performance dashboards
• Operate and evolve Kubernetes infrastructure for hardware-attached worker nodes with job queueing and load balancing
• Monitor system health, perform root-cause analysis, and improve infrastructure resilience and observability

What they're looking for

• Go (production services with HTTP APIs and WebSockets)
• C/C++ (systems-level and test code)
• Python (tooling, automation, scripting)
• Kubernetes (operation, maintenance, queueing patterns)
• PostgreSQL and Redis
• Embedded hardware development and toolchains
• JTAG/SWD debugging
• Power measurement and performance profiling

Benefits

• Competitive salary ($180,000–$220,000)
• Bonus
• Meaningful equity
• Comprehensive benefits

Likely interview questions

• Walk us through your experience bringing up a new embedded hardware platform—what challenges did you face and how did you debug them?
• Describe a time you built production Go services. How did you handle API design, reliability, and scaling?
