Gama

Senior Application Software Engineer

Job description

Rockets have not gotten wider. Satellites need far more power than they used to. The only way through is structures that pack into a fairing and unfold into something massive on orbit.

Gama is building that: ultra-light deployable solar arrays, from 3 kW to over 100 kW, in a factory sized for 100 MW a year. At that scale, we want full traceability of every part and every test, with the hardware recording its own measurements as it is built. This means gigabytes of data per unit, which need to be stored and easy to use.

We are hiring a Senior Application Software Engineer to build the software used to run our factory and our company. For the factory, this covers inventory, work instructions, traceability, and test and telemetry data. For the company, it covers the tools used for purchasing, finance, HR and hiring. You will decide which tools we buy and which we build ourselves, taking into account how much easier AI has made in-house development. This role is separate from our flight software team and focuses on the systems that make the hardware buildable at rate. You will work directly with the VP of Engineering and the COO. Gama operates with extreme ownership: you own the outcome, not just the code.

Your mission will be to:

  • Own the data and system architecture of Gama's factory and business systems: what data we keep, where it is stored and how the systems connect.
  • Build the core manufacturing software: inventory, work instructions, build records and traceability for every unit.
  • Collect production data directly from test stations and machines (test results, telemetry, measurements), at a volume of gigabytes per unit.
  • Make that data easy to search and analyse, so that engineers can quickly trace the history of any unit.
  • Decide for each tool whether to build it or buy it.
  • Connect the company's tools (purchasing, finance, HR, hiring) so that data is entered once and stays consistent.
  • Use AI tools to develop and maintain software efficiently, while keeping the code clean and well documented.
  • Sit with your users: technicians, test engineers, buyers, finance.
  • Keep the tools fast and reliable, since a slow tool on the floor stops production.
  • Design the systems so that a larger team can build on them as the factory grows.

Profile required

  • You are a software engineer who has designed and shipped production systems end to end (data model, backend, interface, deployment) and has owned the architecture of at least one of them.
  • You have built internal software that operational teams use every day to do their work. The industry does not matter: manufacturing, logistics, labs, finance or similar.
  • Strong skills in data modelling and database design.
  • You are comfortable with large volumes of time-series or test data, and with getting data out of machines and instruments.
  • You use AI coding tools daily and review their output critically.
  • Experience both integrating off-the-shelf software through APIs and building custom tools, with good judgment on when to do which.
  • Interest in hardware and willingness to spend time on the factory floor.
  • Roughly 5+ years of relevant experience, but we care far more about what you built than how long you have been working.
  • Professional English. French is a plus, not a requirement.

Nice to have

  • Experience with manufacturing software in a hardware company: MES, ERP, PLM, inventory or traceability systems
  • Experience with test automation, data acquisition or industrial equipment interfaces
  • Experience in a fast-paced hardware startup, ideally within a New Space environment
  • Experience setting up infrastructure, access control and backups for systems that hold sensitive data

This role is probably not for you if your ERP experience is mainly configuring vendor products, or if you prefer to work from detailed specifications. You will be expected to define what is needed and build it yourself.

Company description

Gama is a NewSpace startup based in Ivry-sur-Seine, near Paris. We are developing a next-generation power system for commercial LEO satellites — from solar array power conversion to battery energy storage. We design, build, and test our hardware in-house, and we move fast: our engineers see their designs go from schematic to flight hardware.

We are a small team where ownership matters: you own your subsystem end-to-end, from first calculations to test results. We work hands-on, we help each other without ego, and we treat mistakes as data — finding out why something failed is how we get better.

We offer:
- Your work will fly. Contribute directly to the future of space exploration and Sustainable Space.
- Access to cutting-edge facilities and development opportunities in the heart of the European space industry.
- A steep personal development path, working alongside world class aerospace engineers.
- Equity package and competitive compensation.
- A highly talented, dynamic and international team.
- Relocation support for international hires, where needed.

You do not need to meet every requirement to apply. If this role excites you and you meet many, but not all, of the criteria, we would be glad to hear from you. We value potential and support growth into the role.
