About the role:

We’re looking for a hands-on Developer Experience / Platform Engineer to help build scalable developer enablement solutions in a large, regulated enterprise environment.

Key Responsibilities:

• Build and maintain golden-path templates and reusable patterns that accelerate onboarding and reduce variation across teams.
• Deliver worked examples from real projects (not toy apps) that teams can adopt directly and that double as adoption “media”.
• Improve self-service onboarding so we can scale across company from day one (we can’t and won’t “white glove” every team).
• Run and support feedback loops (office hours, champions networks, Teams/email channels) and turn developer pain points into shipped improvements — either by building the fix or driving it to the right owning team and tracking it to resolution (“not our team” isn’t a resolution).
• Write and improve platform documentation. Documentation is part of our launch gate, and our Definition of Done expects features to ship with it.
• Partner with product, engineering, architecture and risk/control colleagues to ensure guidance is accurate, compliant and practical.

Required Skills & Experience:

• Strong hands-on engineering capability with evidence you can build and deliver: templates, automation, reference implementations, onboarding assets and/or developer tooling.
• A practical understanding of developer experience: how to make the “right” path the easiest path through standardization and automation.
• Confidence writing clear technical content that scales to large audiences.
• Solid production mindset (security, resilience, observability, supportability) so examples and guidance are credible in a regulated environment.
• Good stakeholder and collaboration skills — you’ll work across multiple platform pillars and teams to get outcomes, not just opinions.
