Software Engineer, Integrations (US + Calgary)

Syndio is hiring a Software Engineer, Integrations to build, maintain, and manage integration platforms that enable scalable, reliable, and secure data flows across systems. The role focuses on designing and optimizing workflows, managing connectors and APIs, and supporting integration performance and customer data ingestion.

Responsibilities:

• Build, maintain, and manage our integration platforms, ensuring scalable, reliable, and secure data flows across systems
• 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

Requirements:

• 4+ years building and shipping production software, with solid backend fundamentals
• 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
• You are based in Calgary and legally authorized to work in Alberta without need for additional visa support now or in the future
• Python and/or Go preferred
• Frontend experience (TypeScript/React or equivalent) and interest in building the product surface customers use to connect their systems
• Experience with iPaaS tools (Workato, Boomi, MuleSoft, Tray.io, Celigo) and a point of view on when to build versus buy an integration
• Workflow orchestration engines (Temporal, Airflow)
• File-based ingestion at scale — SFTP, CSV, flat-file pipelines and the validation they demand
• Working with sensitive employee or compensation data and the security and privacy practices that requires
• You've worked with sensitive data and treat security, privacy, and compliance as part of your job rather than someone else's
• You've seen customer onboarding up close and know the ways cross-system data flows go wrong in practice
• You're comfortable in unfamiliar territory — reading a third-party API's docs, tracing a bad record back through a pipeline, and working out what actually happened
• You are a strong communicator, collaborating effectively with both technical and non-technical teams across levels and functions
