Senior Platform Engineer

Experience: 5+ years in Platform Engineering, Infrastructure, DevOps or Site Reliability Engineering.
About the Role

We are building an Internal Developer Portal at Natera , and we are looking for a Senior Platform Engineer to help build it. This is a hands-on software engineering role: you will write the portal, the golden paths that run on it, and the integrations underneath, not just configure someone else’s tooling.

It is a genuine build, but not a blank page. A great deal of capability is already in production, reached today through hand-triggered GitLab pipelines, purpose-built internal UIs and wiki pages that carry the steps and the caveats. A significant part of this role is bringing that capability into the portal as first-class golden paths, re-envisioned rather than wrapped. A new interface over an old workflow does not get adopted. You will join an established Infrastructure Provisioning team inside a larger Platform Engineering organization, building alongside the engineers delivering it and working with the senior engineers who set technical direction.

Success is measured by one thing above all others: Developer adoption.
What You'll Do
Build the Internal Developer Portal

-
Platform Foundation: Contribute to the implementation of the portal platform, then take a major hand in developing and operating it as a product with real users, measured adoption and a roadmap.

-
Service Catalog: Build a reliable system of record for our services and infrastructure, with ownership, relationships, and automated ingestion from source-of-truth systems rather than manual upkeep. A catalog nobody trusts is a catalog nobody uses.

-
Integrations and Extensibility: Build the integrations that connect the portal to our cloud accounts, CI/CD systems, secrets management and internal APIs, and help document the patterns so other engineers can contribute integrations of their own.

Build Golden Paths, and Help Others Build Theirs

-
Work Within the Framework: Help shape the golden path framework and build within it, using the templates, scaffolding, standards and guardrails the team defines, with networking, security, observability and compliance pre-wired in so every path inherits them.

-
Build the Provisioning Paths: Be one of the main builders of the Infrastructure Provisioning golden paths. They are also the reference implementations other teams copy, so the quality of your work sets what others follow.

-
Support Other Teams: Many golden paths will be built by the teams that own the domain. Help them do that well through worked examples, documentation, pairing and reviewing their contributions.

-
Incorporate What Exists: Reimagine today’s pipelines, internal UIs and documented procedures as portal-native journeys, some built here, many by the owning teams. Start from how they are actually used, not how they are written up.

-
Retire the Old Path: Work with the teams who built these tools, since their buy-in decides whether a path is used or bypassed and they are often the right owners of the replacement. Decommission what it supersedes so the platform gets simpler over time.

-
AI-native Platform: Help make the platform readable by AI coding agents as well as people, with structured metadata, documented interfaces and tooling agents can consume, so AI-assisted development meets Natera standards by default.

Drive Adoption

-
Adoption First: Prove the first golden paths against real high-frequency workflows, support teams through onboarding, and prioritize on measured friction rather than preference.

-
Measurable Standards: Help build the scorecards that make platform and compliance expectations visible, and work with consuming teams to close the gaps they surface.
