About the team
We are looking for a curious and experienced Senior Software Engineer to join our Scale - Platform team. We believe that engineers shouldn’t need to choose between being productive and delivering business impact.

In the Engineering Enablement function, your role serves as a catalyst for empowering our engineering teams to innovate and excel. Our team plays a pivotal role in enabling our engineers to streamline their workflows, expedite product delivery, and foster a culture of continuous improvement & engineering excellence. By implementing best practices and open source standards, and facilitating knowledge sharing initiatives, the Engineering Enablement team empowers our engineers to tackle complex challenges with confidence and efficiency, ultimately driving the success and scalability of our platform.

- Contributing to platform APIs, reliability, and cross-cutting features like access control, observability, and CI/CD
- Collaborating with design, product and platform engineers to develop systems that scale across the engineering org
- Actively participating in frontend, testing and design system guilds to collaborate and improve frontend reliability and performance of our platform
Who we're looking for
- 5+ years experience as a full-stack engineer with meaningful contributions to platform initiatives
- Strong frontend experience with modern frameworks (e.g., React) and building reliable, intuitive internal tools
- Deep understanding of custom domain experiences, authentication, access control, observability, and CI/CD tooling
- Proficiency in Node.js, Typescript, Docker, and cloud infrastructure (AWS or equivalent)
- Prior experience in platform engineering, internal tooling, or developer experience teams highly preferred
- Experience with SSO/SAML/SCIM or other provisioning/auth patterns, and familiarity with building tools for secure PII handling, test data, or permissions systems preferred
We're a lean team, so your impact will be felt immediately, and opportunities will grow as the company scales up. If this all sounds like a good fit for you, why not join us?
