Senior Software Engineer (Platform)

Join Fresco, a leading smart kitchen platform, as a Senior Software Engineer. In this role, you will drive the design and evolution of KitchenOS, our multi-sided smart kitchen platform. You will work alongside a strong platform team, shape the architecture of ~20 event-driven microservices, and own schema and API design. You will also have the opportunity to mentor and grow the team's skills. This is a deep-IC, design-first role that requires strong AWS and fluent Python skills, as well as a system-design mindset.

Missions

• Contribuer à la conception et à l'évolution de KitchenOS, une plateforme de cuisine intelligente multi-facettes, en travaillant sur l'architecture de microservices.
• Assumer la responsabilité de la conception des schémas et des API, et améliorer les abstractions partagées sur lesquelles toute l'équipe dépend.
• Participer à la rotation d'astreinte pour les services que vous construisez, en veillant à ce qu'ils soient bien surveillés et maintenus.

Profil recherché

- Strong AI engineering practice: AI tooling is a core part of your workflow, and you can bring the team along on adoption

- Can read IoT/embedded protocol code (CBOR, KSUID, CRC) without panicking

- Strong infrastructure-as-code ownership. We use AWS CDK (writing constructs, not copy-pasting templates); deep Terraform experience transfers well and is equally welcome

- Comfortable across DynamoDB, Valkey (Redis), PostgreSQL (SQLModel/Alembic), and Elasticsearch

- Typically 5+ years designing and building backend systems at scale, with significant time on AWS, spanning services, events, and architecture trade-offs, not just individual functions. We care more about the depth of what you've designed than the exact year count

- Fluent in Python with strict typing (Pydantic v2, pyrefly)

- Appliance/IoT protocol knowledge

- LLM integration (prompt pipelines, structured extraction)

- Multi-tenant SaaS platform experience
