The Senior Backend Engineer will own and evolve identity and access management systems, including authentication, single sign-on, provisioning, session management, MFA, and API key infrastructure. The role also focuses on enterprise readiness, operational reliability, security compliance, technical direction, and mentorship.
Responsibilities
- Own LaunchDarkly’s authentication surface end to end — single sign-on, SCIM provisioning, login and session flows, multi-factor authentication, and API key and token authentication
- Build the enterprise identity capabilities our largest customers require: additional identity-provider integrations, support for multiple IdPs per account, and MFA enforcement by default
- Make the stack operable: SLOs, monitoring for certificate expiry and provisioning failures, actionable alerting, runbooks, and a sustainable on-call
- Partner with Product Security on threat modeling, audit logging, and compliance requirements including SOC 2 and FedRAMP
- Set the technical direction for identity at LaunchDarkly, and raise the bar for the engineers around you through design review and mentorship
Skills
- 6+ years of professional software-engineering experience, with significant work on complex backend applications
- Experience building or operating production authentication and identity systems
- A track record on systems where correctness and availability are non-negotiable, and the habits that come with it: backward-compatible change, staged rollouts, and safe cutovers
- Proficiency in at least one backend language (Go, Rust, Python, etc.) and familiarity with cloud infrastructure (AWS or equivalent), plus strong production ownership including on-call
- Protocol depth in SAML, OIDC/OAuth2, or SCIM, and integration experience with Okta, Microsoft Entra ID, Google Workspace, OneLogin, or Ping
- MFA/WebAuthn, RBAC and authorization policy engines, or audit logging at multi-tenant scale
- Engineering under compliance regimes such as SOC 2 or FedRAMP
