We are seeking a Software Developer to build, maintain, and manage our integration platforms, ensuring scalable, reliable, and secure data flows across systems. This role is crucial as integrations become central to our service delivery. You will be responsible for designing, building, and optimizing workflows, managing connectors and APIs, and providing ongoing support for integration performance.

At its core, this role is about transforming how data flows at Syndio and building the future of all data ingestion across the company.

• Build the front door to Syndio — Data Hub is where every customer starts and the foundation every analysis runs on, so you'll decide how they connect a system, map their fields, and see exactly what came through.
• Keep it fast at scale — customer datasets run to hundreds of thousands of employees across dozens of sources, and holding refresh times as that grows is a standing engineering problem, not a one-time fix.
• Integrate against HRIS, ATS, and payroll APIs, building the platform's native connections and handling the real-world mess of auth flows, pagination, rate limits, schema drift, and partial failures.
• Make failures legible by turning opaque sync errors into clear, actionable feedback so customers and Customer Success can resolve issues without an engineer in the loop.
• Improve the implementation platform, collaborating with Forward Deployed Engineering and Implementation to understand what customers need and grow the platform's capabilities to meet more of it out of the box.
• Work across a real distributed system spanning a Go API, Temporal workflows, a Python transformation engine, and a customer-facing frontend, following problems wherever they lead instead of stopping at a service boundary.
• Raise the standards by establishing the patterns, documentation, and error‑handling conventions that let integrations scale past what any one person can hold in their head.

• 4+ years building and shipping production software, with solid backend fundamentals. Python and/or Go preferred.
• Hands‑on experience building or maintaining integrations against third‑party APIs — REST/SOAP, webhooks, OAuth and API‑key auth, pagination, rate limiting, and handling upstream schema changes.
• Experience with data pipelines and orchestration: scheduling, retries, sequencing, and monitoring workflows across systems.
• Solid SQL and the ability to reason about data models and transformations.
• Familiarity with HRIS, ATS, CRM, or ERP systems and their data models.
• Strong documentation habits and a bias toward making your work legible to others.
• Excellent collaboration and communication skills across technical and non‑technical teams — you'll work directly with Customer Success and Implementation.

• Frontend experience (Type Script/React or equivalent) and interest in building the product surface customers use to connect their systems.
• Experience…
