Embedded Software Engineer

Battery Technology Solutions for a Clean Energy Future

Stafl Systems is dedicated to advancing all applications of lithium-ion battery technology to achieve a clean energy future. Since 2010, we’ve partnered with industry leaders to push the boundaries of innovation across electric vehicles, aviation, marine and consumer products. Our team brings proven engineering expertise across technical consulting, rapid product development, in-house prototype fabrication and battery pack manufacturing to solve some of the most complex challenges in today’s cleantech industry.

We are seeking a Staff Embedded Software Engineer to help set the technical direction for embedded software across our BMS and powertrain programs. Working alongside our other staff engineers, you will share ownership of the embedded platform architecture, help make and defend key technical decisions, and serve as a technical authority that customers and internal teams turn to on the hardest problems, from safety-critical design to hardware/software trade-offs.

Beyond your own technical contributions, you will multiply the effectiveness of the team by mentoring engineers, leading design reviews, and helping define the standards, tools, and processes that let us ship reliable, safe software at speed.

• Co-own the embedded software architecture for BMS and powertrain platforms with peer staff engineers, from hardware abstraction layer through application frameworks, and drive architectural trade‑off decisions in the areas you lead
• Define module boundaries, interface contracts, and reusable platform components that scale across customer programs
• Shape and drive the embedded software technical roadmap together with peer staff engineers and engineering leadership
• Lead technical design reviews and serve as an approving reviewer for architecture and safety-relevant changes
• Lead complex, multi-subsystem efforts from concept through validation, coordinating across firmware, hardware, systems, and test
• Write and review high-quality Modern C++ (C++17+) production code, and help maintain the coding standards and best practices the team follows
• Own requirements definition, work breakdown, estimation, and development planning for the programs and subsystems you lead
• Anticipate and drive resolution of technical risks across hardware/software integration and at the system level
• Define and evolve the HIL validation and test strategy, including test infrastructure, coverage goals, and CI integration
• Serve as a senior technical point of contact for customers on architecture, integration, and technical trade‑offs
• Mentor and develop engineers through design guidance, code review, and technical coaching
• Maintain and evolve the software functional safety strategy, including safety architecture, safety mechanisms, and work products, in support of ISO 13849, IEC 61508, and ISO 26262 compliance
• Communicate technical direction, status, and risks to engineering leadership, customers, and cross‑functional stakeholders
• Evaluate and introduce tools, processes, and technologies that improve development velocity and software quality

• 8+ years of professional embedded software development experience, including significant time as a technical lead or architect
• Proven track record defining and owning the software architecture of complex embedded products shipped to production
• Expert-level Modern C++ for resource‑constrained, real‑time systems
• Deep understanding of embedded C++ tool chains (build systems, compilers, static analysis, debugging environments)
• Deep understanding of microcontroller architecture and real‑time operating systems, including scheduling, memory, and timing analysis
• Demonstrated…
