Full-Stack & Systems Software Engineer
Job Description
At Ansync Labs, we build complete systems under one roof. Our team spans software, PCB design, electrical engineering, mechanical engineering, and precision machining. As a software engineer here, you aren't isolated behind a desk writing abstract code – you operate at the center of a multidisciplinary engineering team, working directly alongside electrical, mechanical, and fabrication engineers to bring physical systems to life.
\n
We partner with fast-paced startups, defense contractors, research institutions, and independent inventors while actively running internal R&D in cutting-edge electronics, computer vision, and operational tooling. We’re looking for engineers who live and breathe getting hands-on with technology and building complex systems in a dynamic, high-velocity environment.

WHAT YOU'LL DO
\n
- \n
- Architect and build solutions ranging from embedded firmware and IoT devices to web/mobile applications and cloud backends.
- Work directly with hardware engineers, machinists, and clients to turn high-level concepts into reliable, production-ready systems.
- Implement rigorous testing strategies (unit, integration, and hardware-in-the-loop) to ensure stability, safety, and performance.
- Utilize AI-assisted development tools (like Claude Code) to accelerate execution, focusing your creative effort on system design, logic, and verification.

WHAT WE’RE LOOKING FOR
\n
- \n
- Strong technical communication skills with a team-first approach to problem-solving, code reviews, and working across hardware and software boundaries.
- Hands-on experience with C on embedded platforms (STM32, nRF52, ESP32) and modern software stacks (JavaScript, Node.js, Flutter, GCP, Firebase).
- Experience writing Verilog for FPGA platforms (e.g., Lattice, Altera) to interface with microcontrollers and custom hardware.
- Deep understanding of testing methodologies and how to verify that complex systems behave reliably in production.
- Practical experience integrating AI coding tools (Claude Code, Copilot, etc.) into your workflow while maintaining high architectural standards.
- A drive to understand how things work under the hood, with the confidence to take ownership of open-ended problems and learn unfamiliar tech on the fly.
