Technical Lead - RTOS, Embedded Systems and Middleware

📍 Location: Paris, France (hybrid or remote within France and Germany possible)

To support its growth and international expansion in Europe and North America, eSOL is looking for a Technical Lead to join its European team, based in Paris. This role is central to eSOL's Full Stack Engineering strategy and part of our long-term commitment to building a strong, technically autonomous European presence.

The company offers challenging projects, a collaborative and international work environment, and the exciting opportunity to influence and shape the future of embedded software for cutting-edge applications across multiple industries.

Main responsibilities

As a Technical Lead at eSOL Europe, you will work closely with and report to the VP of Customer Solutions and Engineering. You will play a pivotal role in leading and mentoring a growing team of embedded software engineers.

You will serve as the technical backbone of the team, actively contributing to development activities while driving best practices, architectural decisions, and internal coordination. You will also support and implement strategic initiatives coming from management, act as a sparring partner for technical decisions, and represent the European engineering function in cross-regional discussions.

This position combines hands-on coding, technical mentorship, and system-level architectural thinking in embedded and safety-critical systems, with exposure to middleware technologies like ROS/ROS 2, AUTOSAR, and others.

Duties of the role will include:


  • Lead and mentor a small, growing team of embedded software engineers in the Paris office.
  • Work closely with the VP of Engineering to drive implementation of technical strategies, team processes, and customer project execution.
  • Contribute directly to software development in C, modern C++ (C++14 and beyond), Rust, and Python.
  • Guide the team through architectural reviews, code design, debugging, and tooling decisions.
  • Participate in code reviews, architecture discussions, and technical troubleshooting, both at low level (e.g. RTOS kernel code, device drivers) and higher level (e.g. middleware, communication stacks and customer applications).
  • Foster a knowledge-sharing culture and support ongoing internal initiatives such as our weekly Tech Learning sessions.
  • Collaborate with our global teams (Japan, Germany, and partners in APAC or NA) to ensure smooth integration with company-wide projects.
  • Support hiring and onboarding of new engineers as we continue expanding.
