Staff Software Engineer - Backend (Permanent Contract)

As a Staff member at Matera, you will contribute to defining the backend technical vision and implementing it: you will set the standards, improve the DevX, and initiate structuring projects so that we build a higher quality product with greater velocity. Your impact will be measured across the entire technical team.

Specifically, your missions will be:

• Define and evolve Matera's backend architecture long-term — modularization, design system, performance, clean architecture, DDD, etc.

• Identify current technical limitations, propose solutions, and implement them with the team

• Initiate and lead high-impact tech or product projects

• Establish and promote backend code standards across all squads

• Improve Developer Experience: AI adoption, tooling, CI, testing strategy, conventions, documentation

• Mentor developers of all levels, elevate the collective skill level

• Contribute to the overall technical vision alongside the CTO and other Staff members

Our Stack:

• Frontend: React, Typescript, React Native (mobile), Jest, Playwright, Maestro

• Backend: Ruby on Rails, Sidekiq, Rspec, Cucumber

• PostgreSQL, Opensearch, Redis

• Infrastructure: Kubernetes, Terraform

Our Organization:

Autonomous Squads – Squads of 5 developers with an EM, responsible for end-to-end maintenance of their domain, but also involved in very different domains for new feature creation.

AI-first – 100% of the code is generated by AI via Cursor and a plan orchestrator integrated into the repository. This is not a bonus, it's our way of working. We expect you to master these tools and know how to get the best out of them.

Collective Intelligence – Developers get involved early in product discussions. Being proactive is an expectation, not a bonus.

Pragmatism & Efficiency – Methodology close to Kanban. We deliver, we learn, we improve.

Flexibility – Flexible hours, remote possible with 2 days of office presence per week.

Adaptability – Our industry evolves quickly, and so does our organization. You must be comfortable with change, even seek it out — someone who is stimulated by novelty rather than destabilized by it.

Benefits:

Compensation: from €88,000 depending on profile and experience,

Location: Paris, Lyon, Annecy, Bordeaux, Marseille, Toulouse

Contract: Cadre forfait jour (Executive package with fixed working days)

• Transparent internal compensation policy.

Quality of Life

• Parental support policy: a gentle return to work at 80% for 4 weeks (paid at 100%), as well as 5 additional days of leave per year for sick children,

• Responsible Commute Time (TTR): 1 additional paid day off per year to favor responsible transportation for your vacation travel,

• Menstrual leave

• Sports: access to WellPass for affordable sports activities,

• Cultural deals with the Leeto platform (discounts for cinema, museums, amusement parks...).

Legal Basis

• Paid leave and RTT (Reduction of Working Time)

• Health insurance & Swile Card - 50% covered

• 100% coverage for provident fund

• Holiday bonus (SYNTEC)

• 50% coverage for transportation costs
