Software Development Engineer Staff
Confirmed on the employer's own hiring board on Oct 8, 2026. First seen by Alion on Jun 6, 2026.
Join our team as a Senior Platform Engineer, where you will own the inner loop of our developer platform. You will design and ship opinionated, production-grade tooling that streamlines the development process and reduces time-to-first-commit. This role requires extensive experience in platform engineering and developer experience, with a strong understanding of container runtimes and environment parity patterns.
Missions
- Conception et construction d'un moteur de scaffolding composable qui génère des dépôts, des pipelines CI/CD, des tests de base, des configurations et des intégrations de plateforme à partir de schémas de service déclaratifs.
- Définition et maintenance de la spécification de schéma qui capture le type d'application, le runtime, les dépendances, les tests par défaut et l'intention d'infrastructure dans un format standardisé et versionné.
- Construction et maintenance de bibliothèques partagées versionnées pour les préoccupations transversales - journalisation, cryptage, auto-configuration, propagation de traces, et images de base Docker.
Profil recherché
- Hands-on Terraform experience for infrastructure generation and self-service provisioning patterns- Strong in Go or Python; deep fluency with GitHub Actions for CI/CD pipeline generation and automation
- Experience with OPA or equivalent policy-as-code engines integrated into build and deploy workflows
- Experience designing and maintaining template lifecycle systems: versioning, migration paths, backward compatibility, rollback safety
- Comfortable working across the stack from schema design through to CI integration and portal plugin surfaces
- Production experience building developer platform tooling - repo generators, CI/CD scaffolding frameworks, devcontainer or ephemeral environment automation - not just consuming them
- Familiarity with schema validation tooling and CLI-first developer experience design
- Strong understanding of container runtimes, base image management, and environment parity patterns (devcontainers, Docker Compose, Kubernetes)
- 7+ years of software engineering experience with at least 3 years in a platform engineering or developer experience role at a mid-to-large engineering organization
- Familiarity with enterprise compliance requirements (audit trails, change evidence, vulnerability scanning integration) is a plus
- Has designed and operated opinionated golden-path systems at scale - the kind that hundreds of engineers depend on daily. Background from companies with strong platform cultures (e.g., Spotify, Netflix, Stripe, Uber, Airbnb) is strongly preferred
- Track record of reducing developer toil through automation, not just documentation or guidelines
- Able to work cross-functionally with security, CI/CD, and application engineering teams to align on standards without creating bottlenecks
- Experience with Backstage or similar developer portal frameworks is a plus
- Strong written communication skills - this role produces tooling that must be self-explanatory, and documentation is part of the deliverable
