Software Engineer

At Perk, our Identity Experience squad owns how users get into Perk and stay in sync. Your work will span SCIM 2.0 provisioning, HRIS integrations (BambooHR, Workday, Merge.dev and more), user lifecycle management, and our calendar service. You'll build the reliable, fault-tolerant pipelines that enterprise customers depend on to keep their workforce data accurate and their employees unblocked from day one.

You'll take real ownership of the features and systems you build - from writing and shipping backend code through to deployment, observability and ongoing reliability - and you'll see directly how your technical decisions affect the onboarding and day-to-day experience of customers across the globe.

How we work

You'll join our Identity Experience (Acquisition) squad, a cross-functional team where engineers have genuine ownership of Perk's user provisioning and identity integration domain. You'll work closely with our Identity Core squad and customer success team, and occasionally engage with enterprise customers to understand how integrations should be designed, delivered and maintained.

AI at Perk

AI is embedded in how we work and what we build. On the engineering side, it spans the whole workflow: our Notion, Jira, GitHub and Slack are AI-connected so you get up to speed fast, and day-to-day it helps with specifying features, writing and reviewing code, and automated AI PR review on every pull request. We also embrace agentic coding, using AI as an active collaborator, not just a prompt-by-prompt co-pilot. We expect candidates to use AI tools in our coding interviews.

Some examples of what you'll do as a Software Engineer at Perk

• Build and ship integrations. You'll implement and maintain HRIS connectors, handling the messiness of third-party APIs - inconsistent schemas, unreliable uptime, and evolving vendor behaviour. You'll write clean, well-tested code that holds up in production.
• Own the full cycle. From picking up a ticket through to deploying a fix or feature, you'll see your work all the way through - including adding structured logging, writing tests, and making sure sync failures surface clearly rather than silently.
• Solve real engineering problems. You'll work on background job processing, state management, data normalisation across third-party schemas, and making provisioning pipelines resilient to failure. These are meaty backend problems with direct customer impact.
• Collaborate and grow. You'll contribute to design discussions, give and receive code review feedback, and work with more senior engineers to develop your technical skills - particularly around distributed systems and integration patterns.

Do you have experience in Workday?, We know the best person for this role might not tick every box below. If you're excited about the problem and bring most of these skills, we'd encourage you to apply.

• Backend Engineering: 4+ years building production backend systems. Comfortable with background job processing, state machines, and working with external APIs that don't always behave as documented.
• Integration Experience: Has built or maintained third-party integrations - REST APIs, webhooks, data sync pipelines - and understands the failure modes that come with depending on external systems.
• Data & Schema Handling: Experience normalising and mapping data across inconsistent schemas; comfortable writing migration plans that don't break production.
• Operational Awareness: Writes code with observability in mind - structured logging, sensible error handling, and alerting that helps the team spot problems before customers do.
• Testing Discipline: Writes meaningful unit, integration and contract tests; understands the difference between coverage and confidence.
• Collaborative Working Style: Gives and receives feedback well, asks good questions in design reviews, and communicates clearly about progress and blockers.
• AI-Driven Development: Experience with or strong interest in modern AI-augmented workflows and agentic coding.
