Staff Software Engineer - IAM (Platform Engineering)

Description
Position Summary
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, DevOps, 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.
Location & Work Arrangement
This role is remote, however, the candidate(s) will be expected to relocate at their own expense to our onsite Houston location by Q1 in 2027*
Q1 2027 is an approximate timeframe and is subject to change at any time
Responsibilities
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 lifecycles
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
Required Qualifications
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 ID, Okta, Ping Identity, ForgeRock) 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, CloudFormation)
Familiarity with Zero Trust, least privilege, CI/CD, DevSecOps
Experience with distributed systems and containers (Docker, Kubernetes)
Ability to travel up to 10%
Preferred Qualifications
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)
