Connect the systems & Build the standard. The hardest part of integrations isn't writing the code. It's making sure it holds up long after launch, and that the next integration doesn't take as long to build. At Simployer, our API & Integrations team builds the standard integrations that connect our platform to the external systems our customers already use: ATS, CRM, Payroll and Time Reporting. As we expand into new markets, the goal is to continue building standard integrations that are self-served: customers set up and manage these connections themselves, and each new integration is faster to build and easier to reuse. Simployer is also at the forefront of AI, and it shows in how we work day to day. We use AI development tools daily, not just as chat assistants but built into our coding workflows, and we experiment constantly through hackathons and internal tools we build to solve our own problems. Our team also owns Simployer's public MCP built on top of our public API, part of how integration is expanding to include AI agents, not just traditional systems. Your mission Build integrations that customers can set up themselves and trust to sync their data accurately across systems. Reliable enough that they hold up as we scale, standard enough that each new connection is faster to build than the last. You will take ownership of real integration work: building and maintaining integrations to the external systems customers depend on, ATS, CRM, and payroll among them, and standardizing the patterns behind them so integration becomes repeatable rather than bespoke. You will also extend the public API that partners and third-party vendors build on, helping grow the ecosystem around Simployer's data. You will at times work closely with other product teams at Simployer, those responsible for the Absence, Compensation, and Core domains, along with the customer support and professional onboarding teams that help our customers succeed. You will thrive here if… You have real experience across more than one tech stack and can go deep in whichever one the work calls for. Our platform runs on Java and Spring Boot today, alongside inherited integrations in the Node.js ecosystem you'll help maintain, and picking up new languages and frameworks doesn't slow you down Working across the frontend (React), backend (Java, Spring Boot, TypeScript), and database (MongoDB, PostgreSQL) feels natural You have built or worked with REST APIs and understand what makes an integration reliable versus fragile Integration patterns and external systems aren't new to you You have worked with external systems with unreliable or missing documentation and found a way through AI development tools are already part of your daily work, or personal projects you can walk us through, real and current, not something you're planning to start You enjoy working through challenges with other teams, and can explain an integration issue just as clearly to a developer as to an HR person who has never opened an API doc Tech you'll be working with: Java 21+, Spring Boot, TypeScript, Node.js, Apache Camel, React, GraphQL, PostgreSQL, MongoDB, Kubernetes, and cloud (Azure and GCP). This is a mid/senior level role, but if you feel it's a good fit, strong integration experience carries more weight than total years, go ahead and apply!
