Senior Backend Engineer – Users Infrastructure

As the founding member of the Users Infrastructure team in India, you will architect the foundational security and identity substrate that every Weave product depends on. You will lead the transition from legacy authorization to a modern, globally distributed Identity and Access Management (IAM) platform powered by SpiceDB and Go. This is a high-leverage role requiring a blend of secure backend engineering and the leadership maturity to grow a new regional hub for a Tier-1 infrastructure unit.

• This position will be remote
• Reports to: Manager of Engineering - Users Infrastructure

What You Will Own

• The Identity Lifecycle: You will own the core services responsible for authenticating every entity—human and machine—within the ecosystem. This includes managing the trade-offs between stateless scalability and real-time session revocation.

• Authorization Strategy: You will be defining how fine-grained permissions are modelled, inherited, and enforced across a massive, multi-tenant hierarchy of organizations and locations.

• The "Paved Road" for Developers: You will own the internal SDKs, gRPC contracts, and middleware that allow over 150+ downstream engineers to integrate security features into their products without needing to be cryptography experts.

• Enterprise Integration Standards: You will manage the infrastructure that bridges our platform with the world, including federated identity (SSO), automated provisioning (SCIM), and secure machine-to-machine (M2M) communication protocols.

• Operational Excellence: Improve system observability (MTTD/MTTR) by integrating monitoring and load-testing protocols into our Tier-1 services.

• Systemic Integrity & Compliance: You are the guardian of the "Source of Truth." You will own the immutability and reliability of our audit logging pipelines and the consistency of identity data.

• India Team Trajectory: As a founding member of the regional hub, you will own the technical bar and operational culture for the India-based arm of the team, ensuring seamless asynchronous collaboration with the US-based team members.

What You Will Need to Accomplish the Job

• Experience: 5+ years of backend engineering with significant time spent building distributed systems in

Go

.

• Domain Expertise (in any or all of these areas): Deep understanding of AuthN/AuthZ primitives: OAuth 2.0, OIDC, SAML, and JWT mechanics.

• System Design: Proven ability to manage complex data migrations, distributed architecture and build gRPC-based microservices.

• Communication: Exceptional written clarity; the ability to write Technical Design Documents (TPDs) that bridge the gap between India and US-based stakeholders.

What Will Make Us Love You

• The "Founding" Spirit: You have previously been an early member of a distributed team and understand how to build culture across time zones.

• Security Mindset: You treat "Zero-Trust" as a default, not a buzzword, and have experience with Zanzibar-style authorization or SpiceDB.

• Reliability Obsession: You don't just ship code; you ship alerts, dashboards, and runbooks (and you have a "stop-and-fix" mentality).
