Staff Software Engineer

Syndio is the leading pay governance and compensation intelligence platform. We help organizations make better pay decisions at every stage of the compensation lifecycle, from leveling and offers to promotions and merit. Our platform gives HR, compensation, and finance leaders the data and decision support they need to govern pay fairly, compliantly, and with confidence. We partner with many of the world’s most recognized and respected enterprises, helping them implement leading-edge compensation solutions with expert guidance and analyzing pay for over 10 million employees across the world. Join us in our mission to help companies make smarter pay decisions they can trust You'll work on the problems that cut across the org: building outward-facing surfaces for our platform, building internal tools and agentic solutions that empower teams across the company, and flexing into whichever team needs senior capacity at the time. The common thread is technical depth applied where it has the most leverage, with very little direction required to get there. The largest current thrust is our third-party ecosystem: integration apps hosted inside major HRIS and enterprise service management platforms, and the APIs that external systems and developers build against. Alongside that, you'll own internal tooling and agentic projects that support teams across the company — building on the AI capabilities our AI team provides. You'll also support teams outside your own, including work on our identity and authentication services, where we want more depth on the team. You'll gather requirements directly from senior leaders across the company and at times execute without a product manager in the loop. Success is measured three ways: how much of our customers' work can happen inside the systems they already use, how well the tooling you build supports the teams that depend on it, and how reliably you move the needle on whichever problem you're pointed at. Build and ship integration apps hosted inside third-party platforms — major HRIS, enterprise service management, and the other systems where compensation and HR work actually happens. Own the full lifecycle: platform SDKs and app frameworks, tenancy and installation models, marketplace certification and review, versioning, and upgrades that don't break live customer installs. Agentic Internal Tooling & Projects Build internal tooling and agentic projects that support the org — scaffolding, verification, agents that handle work people currently do by hand, and the harnesses that make any of it trustworthy. Design and build APIs consumed by third-party systems and external developers — with real thought given to versioning, backward compatibility, rate limiting, pagination, idempotency, webhooks, and error semantics that a stranger can debug. OAuth 2.0, OIDC, SAML, token exchange, machine-to-machine credentials, service accounts, and scoped access across tenant boundaries. The data behind our platform is sensitive, and the access controls around it have to be defensible under scrutiny. Partner with technical leaders across the org to set standards — testing, API design, security review, agentic workflow. Sit with senior leaders — engineering, product, GTM, customer-facing teams — and turn a business need into a scoped, sequenced technical plan. At times operate without dedicated product support: gather the requirements, make the call, write it down, and ship it. Translate the technical reality back to non-technical stakeholders in terms they can act on — what's possible, what it costs, what we're trading away. Deep experience in complex, distributed, service-based systems — you're comfortable reasoning about failure modes, data consistency, and latency across service boundaries. Python, Go, Node/JavaScript, TypeScript, React, Postgres, and NoSQL stores such as Firebase. You should enjoy picking up something unfamiliar, building a rough prototype to learn its shape, and being honest about when it isn't the right answer — curiosity paired with the judgment to know when to stop. You've built against third-party platforms before and know what that actually costs — quirky APIs, undocumented behavior, certification processes, and partners who ship breaking changes on their schedule. You've built APIs that developers outside your company depended on, and you understand the discipline that requires. Testing as a first-class skill. Strong end-to-end and integration testing of service-based architectures, with hands‑on experience in an e2e framework (Playwright, Cypress, or similar) and a point of view on how to test systems where the interesting bugs live between the services. You use coding agents daily, you tune how you use them, and you build the harnesses that make them reliable — tight test loops, strong CI/CD gates, spec‑to‑code workflows, and ways of working that produce high‑quality output rather than plausible-looking output.
