Software Product Owner (f/m/d)

Location Reims
Department Electrical and Software Systems
Type Full-Time
Starting ASAP

As Latitude develops and qualifies its launcher, the volume, complexity, and criticality of engineering and operational data continue to grow. The Software Product Owner plays a key role in structuring this digital ecosystem by ensuring that internal software tools, data flows, and configuration information remain consistent, traceable, and aligned with the needs of engineering, testing, avionics, GNC, systems, and operations teams. At the crossroads of software development and operational engineering, this position helps secure the data chain that supports the design, qualification, and execution of Latitude’s missions.

Tasks & missions

  • Gather and assess requirements from user teams: Operations, Testing, Avionics, GNC/OBS, Systems, Analysis.
  • Translate these needs into actionable backlog items: clear problem statements, acceptance criteria, and operational impact if not addressed.
  • Manage and maintain a single, prioritized backlog covering all software tools, aligned with the development and qualification schedule.
  • Arbitrate between competing requests and document decisions and their rationale.
  • Identify whether an issue stems from a tooling need or from a process or usage deficiency.

 

Technical Contribution to Development

 

  • Take ownership of backlog items end-to-end: coding, testing, review, integration, CI, etc.
  • Contribute to the maintenance of deployed software.
  • Ensure acceptance testing of deliverables.

Execution Management and Coordination

 

  • Facilitate team rituals: backlog reviews, sprints, progress meetings, and demo reviews.
  • Ensure the availability of business and technical stakeholders to resolve questions blocking developers.
  • Monitor progress and flag deviations; escalate decisions beyond the role’s scope to the Department Manager, including capacity, cross-team priorities, and subcontracting budgets.
  • Govern the use of AI assistance in CI/CD and software development: define areas where it provides genuine value and those where human review and verification remain mandatory.

Data Chain Consistency

 

  • Ensure consistency of the cross-functional data model. For example, equipment declared in one software tool must be addressable in another.
  • Ensure that the configuration baseline of a mission is captured as native metadata within generated data, as this is essential for subsequent usability and analysis.
  • Maintain an end-to-end view of upstream and downstream dependencies and identify changes that could weaken the overall data chain.

Processes, Quality and Traceability

  • Formalize CDM processes: data lifecycle, approval workflows, change management, and acceptance criteria.
  • Define the verification strategy for tools generating onboard artifacts, such as builders and configuration compilers, where failures may remain silent and propagate downstream.
  • Ensure traceability: for a given mission, identify which version of each database, tool, and file was used.
  • Manage technical debt and keep it visible within the backlog rather than allowing it to accumulate outside formal tracking.

Capacity Planning and Resourcing

 

  • Define recruitment and subcontracting needs: scope, required skills, capacity, and schedule.
  • Raise alerts regarding capacity risks, particularly when critical expertise is concentrated in a single developer (bus factor).
  • Maintain a clear and readable workload and capacity plan for the department.

 

Position Specifics

  • Mainly office-based position.
  • Regular interaction with other departments and projects.
  • Confidentiality level: Normal.

Preferred experience & skills

Education and Qualifications

  • Engineering degree in Embedded Systems, Industrial IT, Data, or equivalent, with experience coordinating technical software development, ideally within the space, aerospace, or testing industries.

Required Knowledge and Skills

  • Experience as a Product Owner or in coordinating a software development team is preferred.
  • Recent hands-on software development experience is required, typically 4-5 years.
  • Operational experience in testing, test campaigns, or qualification campaigns.
  • English level: B2

 

Required Experience

5+ years of professional experience.

The Fluids team at Latitude develops the fluidic ground-side and vehicle-side systems for the launch vehicle. Sub-disciplines within the team include valves, fluidic routing, pressure-control systems, and liquid level sensing systems among others.

These are precise systems posing difficult challenges to overcome, as they deal with the highest pressures and lowest temperatures seen on the entire vehicle. We are looking for motivated candidates that are self-driven and hands-on to join the team as an intern to help us solve these challenges.

In return, you will develop your technical skills and work alongside talented engineers that will be able to guide you toward the next step in your career, both technically and professionally.

Tasks & missions

The intern’s duties will include: Developing fluidic routing for the first and upper stages of the launch vehicle, including design, analysis, material selection, drafting, and assistance with manufacturing and testing.
Write qualification and acceptance plans for vehicle valve components. Assist and, ultimately, lead the execution of these test plans, including pressure testing, cryogenic testing, and vibration testing.
Design custom valves for the vehicle. This project will include the design of different types of valves (electromagnetic, pneumatic, etc.) for use in various rocket systems. The project involves a comprehensive approach to valve design, with a high degree of autonomy but under the supervision of experts in the field.

Preferred experience & skills

Education: Currently studying for a Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering, or equivalent.

Technical skills:

    • Good engineering fundamentals.
    • A strong basis in mechanical and fluidic engineering.

Soft skills:

    • Ability to work well in a fast-paced team environment.
    • Ability to interact well and frequently with other engineers, suppliers, technicians, and managers.
