Software Development Engineer

We are looking for a Senior Platform Engineer to own the inner loop of our developer platform – the scaffolding, environment bootstrap, and shared library systems that determine how fast and confidently engineers go from idea to first commit. This role is foundational: the composable scaffolding engine, declarative service schemas, and template lifecycle systems you build will directly determine whether developers experience a golden path or a maze of tribal knowledge and configuration drift.

You will design and ship opinionated, production‑grade tooling that generates repositories, CI pipelines, baseline tests, and infrastructure hooks from a single schema declaration – and maintain those templates safely over time as the platform evolves. This is not a role for someone who has used golden‑path systems; it's for someone who has built and operated them at scale.

Composable Scaffolding Engine

• Design and build the engine that generates repositories, CI/CD pipelines, baseline tests, configuration, and platform integrations from declarative service schemas with opinionated defaults and extensibility hooks
• Own the full scaffolding surface: repo generator, CI/CD pipeline generator, config manager, secrets/env var wiring, and integration layer into Git Hub and cloud providers
• Ensure generated scaffolds are immediately functional – wired to CI, observability, and infra hooks from day one, with no blank‑page setup required

Declarative Service & Workload Schemas

• Define and maintain the schema specification that captures application type, runtime, dependencies, testing defaults, and infrastructure intent in a standardized, versioned format
• Build validation tooling (CLI and CI‑integrated) to enforce schema correctness and surface errors early
• Reduce time‑to‑first‑commit from the current 18‑40 day range to under one week

Template Lifecycle Management

• Build the versioning, validation, and upgrade system that evolves scaffolds over time while preserving backward compatibility for downstream projects
• Implement three‑way merge logic (template old template new customized service) with rollback safety and customization detection so teams can adopt template updates without breaking builds

Local Dev & Environment Bootstrap

• Build and maintain standardized local and ephemera development environment descriptors (devcontainers, Docker Compose, golden images) with parity validation against CI and target runtimes
• Implement environment automation: just‑in‑time provisioning triggered by pull request, configuration injection for secrets and service discovery, and tear‑down automation
• Implement environment health and drift detection to catch "works on my machine" failures before they reach CI

Reusable Shared Libraries

• Build and maintain versioned shared libraries for cross‑cutting concerns – logging, encryption, auto‑configuration, trace propagation, and Docker base images – as consumable, consistent building blocks for all application teams
• Ensure libraries are secure from inception and reduce fragmentation in security posture and reliability across the service ecosystem

• Production experience building developer platform tooling – repo generators, CI/CD scaffolding frameworks, devcontainer or ephemera environment automation – not just consuming them
• Strong in Go or Python; deep fluency with Git Hub Actions for CI/CD pipeline generation and automation
• Hands‑on Terraform experience for infrastructure generation and self‑service provisioning patterns
• Experience with OPA or equivalent policy‑as‑code engines integrated into build and deploy workflows
• Strong understanding of container runtimes, base image management, and environment parity patterns (devcontainers, Docker Compose, Kubernetes)
• Experience designing and maintaining template lifecycle systems: versioning, migration paths, backward compatibility, rollback safety
• Familiarity with schema validation tooling and CLI‑first developer experience design
• Comfortable working across the stack from schema design through to CI integration and portal plugin surfaces

• 7+ years of software engineering experience with at least 3 years in a platform engineering or…
