Job description

Founded by Arianna Huffington in 2016, Thrive Global is a leading behavior change technology company with the mission to improve productivity and health outcomes - one Microstep at a time. Thrive helps individuals and organizations improve well-being, performance and mental resilience with its AI-powered behavior change technology platform.

For more information, visit www.thriveglobal.com.

This is a high-impact role for a senior engineer who wants real ownership from day one. As a Senior Software Engineer on the Identity team, you will design, build, and operate the systems that underpin sign-up, authentication, and identity across every Thrive product. When an employee at one of our 200+ enterprise customers signs in, your work is the front door.

This is a fast-moving, lean environment. We are looking for someone who brings the pragmatism of a startup, a bias to ship and iterate quickly, paired with the craft of an engineer who has seen the long-term cost of shortcuts.

How You’ll Contribute

• Own and evolve the enterprise identity platform end-to-end - Design, build, and ship the software that onboards, authenticates and authorizes users to the entire Thrive ecosystem. Partner with internal teams to provide the tools & systems to manage a users' identity and enable the mission of Thrive.
• Independently scope and deliver medium-to-large projects - take an ambiguous problem, break it into well-sized workstreams, sequence the work, and drive it to completion with minimal hand-holding.
• Partner closely with Product and stakeholders - translate business requirements into technical plans, surface trade-offs early, and keep cross-functional partners informed throughout delivery.
• Set a high bar for quality without sacrificing pace - bring a bias to ship and iterate fast, balanced with the craft and judgment to avoid costly shortcuts.
• Support reliability and incident response - provide on-call and incident support during US working hours to keep the platform healthy and customers supported.

Qualifications & Skills

• BA/BS degree or relevant work experience
• Senior-level engineering experience with a track record of owning production systems end-to-end.
• Strong Java/Kotlin, ideally full-stack with TypeScript, with experience balancing sustaining engineering (reliability, scalability, technical debt) against net-new feature delivery.
• Experience building and supporting B2B / enterprise-facing software.
• Demonstrated ability to independently scope and deliver medium-to-large projects, from ambiguous problem to shipped solution.
• Experience with on-call rotations and incident response.
• Meaningful daily overlap with US Eastern business hours, plus availability for overlap with our Ireland-based team.

Who You Are

• A self-directed senior engineer who thrives with ownership and minimal oversight, and knows which decisions warrant a stakeholder check-in.
• A pragmatic builder who blends startup speed with engineering craft - you ship and iterate, but you don't accumulate avoidable debt.
• A clear communicator who surfaces trade-offs and risks early and keeps cross-functional partners aligned.
• Energized by ambiguity - you can take a loosely defined problem and turn it into a sequenced, deliverable plan.
• Reliable under pressure, with the judgment to keep systems stable and respond effectively when incidents arise.
• Quality-obsessed without being precious - you set a high bar and still move the work forward.
• Hands-on experience with standards-based identity protocols: OAuth 2.0, OIDC, SAML, and SCIM provisioning.
• Experience integrating with enterprise identity providers (Okta, Entra ID, Ping or similar) and debugging customer SSO configurations in production.
• Familiarity with session management, token lifecycle, and secure credential handling at scale.
• Experience building software in security-sensitive or regulated environments (SOC 2, HIPAA, or equivalent).
