Software Engineer - IAM; Platform Engineering

Description

We are seeking a Staff Software Engineer – IAM to architect, design, and build Identity and Access Management (IAM) services for our multi‑tenant SaaS platform.

This is a software engineering role—not an IT, security administration, or enterprise IAM configuration role. Candidates must have experience designing and building identity services and writing production code.

You will act as a hands‑on software engineer and technical leader, owning the architecture, implementation, and evolution of authentication, authorization, and identity services. You will partner closely with Product Engineering, Security Architecture, Dev Ops, and Compliance to deliver secure, scalable, developer‑friendly identity capabilities.

This is a greenfield/early‑stage role with significant influence over long‑term identity strategy and technical direction.

• Open to candidates based in Santa Clara, CA;
  Seattle, WA;
  Houston, TX
• On‑site role with presence aligned to local team cadence and needs

• Architect, design, and implement IAM platform services enabling authentication and authorization across the SaaS product
• Define and own IAM architecture: identity boundaries, trust models, access patterns, token life cycles
• Build scalable services supporting OAuth 2.0, OIDC, SAML, and SCIM
• Develop APIs, SDKs, and tooling for safe, intuitive consumption by product teams
• Apply least‑privilege and Zero Trust principles across users, services, and infrastructure
• Lead technical decision‑making with clear tradeoffs across security, usability, and performance
• Partner with Security and Compliance for SOC 2, ISO 27001, and NIST alignment
• Drive incident response and root‑cause analysis for identity‑related issues
• Mentor engineers and elevate IAM engineering practices and platform reliability

• 10+ years of software engineering experience, including 4+ years building IAM systems
• Deep expertise with SAML, OAuth 2.0, OIDC, SCIM
• Bachelor’s or Master’s degree in Computer Science, Engineering, or related field (or equivalent experience)
• Experience integrating with IAM platforms (Entra , Okta, Ping Identity, Forge Rock) as an engineer, not an administrator
• Expert‑level proficiency in one or more backend languages (e.g., Java, C#) and in building production services (testing, observability, performance)
• Experience with cloud platforms (Azure, AWS, or GCP) and Infrastructure as Code (Terraform, ARM, Cloud Formation)
• Familiarity with Zero Trust, least privilege, CI/CD, Dev Sec Ops
• Experience with distributed systems and containers (Docker, Kubernetes)
• Ability to travel up to 10%

• Experience building IAM capabilities for multi‑tenant SaaS (tenant isolation, per‑tenant config, scale)
• Background in platform engineering, identity platforms, or security infrastructure engineering
• Understanding of compliance frameworks (SOC 2, ISO 27001, NIST)
