Senior Software Engineer - Identity Experience

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 own these systems end-to-end — from integration architecture 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.

You'll join our Identity Experience (Acquisition) squad who are cross-functional and where you have real ownership of Perk's user provisioning and identity integration domain. You'll work closely with enterprise customers, our Identity Core squad, and our customer success team to shape how integrations are designed, delivered and maintained.

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 it means to be a Senior at Perk:

• Shape the bigger picture. You'll contribute to the integration and provisioning roadmap alongside your PM and EM, deciding not just how we build HRIS connectors, but how Perk's integration platform should evolve to onboard enterprise customers faster, with less friction and fewer surprises.
• Architect for today and tomorrow. You'll write design documents for significant changes to our provisioning and sync systems, accounting for eventual consistency, third-party API instability and the wide variety of data models across HRIS vendors. You'll be a guardian of integration reliability, proactively managing technical debt in our connector layer before it creates customer impact.
• Lead across boundaries. Provisioning touches identity, product, and enterprise customer success. You'll drive alignment across squads on how user state is owned and synced, contribute to engineering guilds, and engage directly with enterprise customers during complex onboarding initiatives.
• Raise the bar for everyone around you. You'll mentor colleagues in integration engineering patterns, give thoughtful feedback in design reviews, and model what great observability and fault-tolerance looks like in a system that depends on unreliable third-party APIs.

Desired skills and experience:

• Product Leadership: Translate complex business goals into technical roadmaps; de-risks ambiguous projects through spikes and prototyping.
• System Architecture: Architects scalable, evolvable sync systems and data models — thinking carefully about eventual consistency, failure isolation and the long-term maintainability of connector-heavy architectures.
• API Design & Platform Thinking: Designs clean, well-documented integration APIs and understands that the integration layer is a product consumed by both enterprise customers and internal teams.
• Backend Excellence: Engineers sophisticated backend solutions involving background job processing, state management across distributed systems, data normalisation across inconsistent third-party schemas, and complex migration plans.
• Operational Maturity: Leads observability practices for integration systems — structured logging, alerting on sync failures, customer-facing error messaging. Defines SLOs and manages incident response for customer-impacting sync issues.
• Technical Standards: Defines and upholds engineering excellence including CI/CD, testing strategies (including integration and contract testing) and coding standards.
• Mentorship & Influence: Levels up the engineering organisation through active mentorship, design reviews and influencing the roadmap with insight from integration complexity.
• AI-Driven Development: Experience with or strong interest in modern AI-augmented workflows and agentic coding.
