This is a senior individual-contributor role, not a people-management role: the Lead Engineer sets technical direction, raises the bar on engineering quality, and multiplies the team's effectiveness through mentorship, architecture, and hands-on delivery, rather than through direct reports. The Lead Engineer acts as the primary technical counterpart to the Senior Engineering Manager, translating team goals and long-term architectural context into concrete technical plans, and representing Platform Services' technical perspective in conversations with other engineering teams and stakeholders. This role requires deep experience with large-scale, object-oriented backend systems, APIs, and interoperability standards, along with the judgment to make and defend significant design and architecture decisions. A background in the healthcare or social care problem space is useful but not required. What You'll Do: * Own and evolve the technical architecture of Platform Services' core APIs and interoperability solutions, ensuring they remain scalable, secure, and maintainable as usage grows. * Lead the design and implementation of complex, cross-cutting technical initiatives (e.g., FHIR-based interoperability, authentication frameworks such as SAML, SCIM, OAuth, and SMART), from proposal through delivery. * Set technical standards and best practices for the team; review designs and code to maintain quality, consistency, and long-term maintainability across new and legacy codebases. * Mentor and grow other engineers on the team, including pairing, technical coaching, and helping less experienced engineers reason through design trade-offs. * Partner closely with the Senior Engineering Manager to translate team vision and business priorities into a concrete technical roadmap, and surface technical risks early. * Represent Platform Services in cross-team technical discussions, building consensus with other technical leads on shared approaches and integration points. * Break down ambiguous or large-scale problems into well-scoped technical plans that others on the team can execute against. * Stay hands-on: contribute production code, especially for the highest-leverage or highest-risk parts of the system. * Contribute to a positive, solution-focused, and collaborative team culture. ## Related Videos - [Psychological Safety in Software Engineering - Jenny-Margrethe Vej & Alexandra Hou Aldershaab](https://www.wearedevelopers.com/videos/2142-psychological-safety-in-software-engineering-jenny-margrethe-vej-alexandra-hou-aldershaab) - [Coffee with Developers: David Heinemeier Hansson](https://www.wearedevelopers.com/videos/875-coffee-with-developers-david-heinemeier-hansson) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Throwing off the burdens of scale in engineering](https://www.wearedevelopers.com/videos/608-throwing-off-the-burdens-of-scale-in-engineering) - [Coroutine explained yet again 60 years later](https://www.wearedevelopers.com/videos/690-coroutine-explained-yet-again-60-years-later) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [The 7 Most Popular Backend Frameworks for Developers](https://www.wearedevelopers.com/magazine/403-the-7-most-popular-backend-frameworks-for-developers) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers)
