Staff Full Stack Systems Engineer – Energy infrastructure

Amperesand • San Francisco, CA

23h • $200,000 - $220,000 • Onsite

About The Position

We are hiring a Staff Full Stack Systems Engineer to build the software that controls, monitors, and orchestrates Amperesand's solid-state power infrastructure products. This includes embedded Linux devices inside our hardware and cloud services that customers use to manage deployments in the field.
This is not a typical web app role. You will work at the boundary where software meets physical infrastructure and you need to be comfortable in that space. You will work on things like hardening our Yocto based OS, building services to handle all the telemetry from our products, and creating dashboards to help visualize our product and its performance.
You will sit within a small engineering team and collaborate daily with power electronics firmware engineers, control engineers, and other software engineers. We ship software that runs on real energy systems. Reliability, safety, and correctness are not aspirational values here. They are hard constraints.

Requirements

• 5+ years of experience
• Experience shipping and maintaining production software systems that interact with physical hardware or industrial equipment, not just web services
• Strong C, Go, and or Rust background, with ability to reason about memory management, concurrency, and performance tradeoffs in production
• Experience working deeply on Linux systems, not just deploying containers, including debugging kernel interactions, profiling performance, or working with device drivers
• Hands-on experience with at least one Linux build system such as Yocto, Buildroot, Bazel, or CMake, with ability to explain pain points and how you worked around them
• Experience building and operating backend services, APIs, and data pipelines that remain reliable under real operational constraints, not just “five nines on paper”
• Disciplined software development practice including version control, CI/CD, automated testing, and thorough code review as standard workflow habits
• Ability to communicate clearly with non-software engineers such as firmware engineers, field technicians, and hardware designers, and translate across those boundaries

Nice To Haves

• Experience in energy, power electronics, grid infrastructure, or industrial controls, with ability to speak credibly about SCADA, grid-tied inverters, battery management systems, or substation automation
• Experience working on real-time or safety-critical systems where failure modes have physical consequences
• Experience working with time-series telemetry at scale, such as device fleets producing thousands of data points per second, with understanding of storage, query, and visualization challenges
• Experience with communication protocols used in energy infrastructure such as Modbus, DNP3, IEC 61850, or similar standards

Responsibilities

• Architect and maintain full-stack software systems that directly interface with Amperesand's grid-connected power hardware — this includes edge device software, backend services, and operator-facing tools
• Build and operate high-performance backend services and APIs in C, Go, and/or Rust for hardware control, telemetry ingestion, and system orchestration
• Develop internal tools and dashboards that surface device health, alarms, telemetry trends, and deployment status for both engineering and field teams
• Own and improve the Linux build pipeline (we use Yocto and CMake today) to produce repeatable, reproducible images for our edge devices
• Write software that must run reliably on resource-constrained Linux-based edge hardware as well as in cloud environments — and understand the tradeoffs between the two
• Integrate with embedded firmware, real-time data pipelines, and hardware control layers, including protocols common in energy infrastructure (e.g., Modbus, DNP3, or similar)
• Own software quality end-to-end: testing, code review, CI/CD, production monitoring, and incident response for systems that control real power equipment
• Collaborate with power electronics and infrastructure teams to define system interfaces, data contracts, and long-term technical direction
• Mentor other engineers and provide technical leadership on architecture decisions, performance optimization, and reliability engineering

Benefits

• Competitive Salary + Incentive Stock Options
• Medical, vision, and dental benefits for employees and their dependents, effective from the start of hire
• Company paid Basic Life, AD&D, short-term and long-term disability insurance
• 401k retirement savings plan through Empower
• Employees receive paid time off (PTO), paid sick days, and paid company holidays
• Commuter Benefits
• 100% paid maternal leave (12 weeks) and paternal leave (6 weeks)
• Singapore-based employees receive benefits in accordance with local government provisions.
