Front-End / StencilJS Software Engineer

Greetings, Future Tech Expert

3Pillar General is modernizing a complex, security-critical front-end estate — six micro-frontend applications on Azure Kubernetes Service — for a major institutional client. The work converts five Angular and AngularJS applications to StencilJS and hardens a sixth, eliminating approximately 160–170 known vulnerabilities and replacing end-of-life frameworks with a modern, supportable web-component model.

This is a hands-on engineering role built for someone early in their career who is ready to grow fast in a structured, AI-assisted delivery environment. You will work inside a small, high-velocity build pod — alongside a Tech Lead and a Senior AI Engineer — delivering real production code against real client constraints. The work is guided by a spec-driven methodology and supported by AI agentic tooling, which means you spend less time on boilerplate and more time learning how quality software is built and reviewed.

Key Responsibilities





• Convert Angular and AngularJS applications to the StencilJS web-component model from pod-produced specifications, one application per build cycle.
• Author StencilJS unit tests, treating test coverage as a first-class deliverable (target ≥ 75% per application).
• Integrate applications against client-owned back-end APIs using mocks and a strangler-fig cutover, flagging integration discrepancies against the spec early and keeping front-end delivery independent of back-end change.
• Deliver each application build-ready and test-ready in the client’s test environment, meeting code-quality and vulnerability-scan requirements (no Critical or High findings).
• Provide accurate status tracking, reporting, and estimation using project methods and tools.
• Gather requirements, validate their understanding amongst the team, and create and maintain relevant documentation.
• Execute activities within the current methodology and uphold the highest quality standards.
