Senior Backend Engineer

Role Description

As a Senior Backend Engineer on our Users Infrastructure team, you'll join a high-trust, high-impact team helping to shape the future of healthcare technology. You will architect the foundational security and identity substrate that every Weave product depends on. 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.

You’ll thrive here if you care deeply about customers, lead with curiosity, and live by our core values:

• Think creatively.
• Stay hungry.
• Do the right thing.
• Care more.
• The customer is everything.

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

What You’ll Own

• The Identity Lifecycle: You will own the core services responsible for authenticating every entity, human and machine, within the ecosystem.
• Authorization Strategy: You will be defining how fine-grained permissions are modeled, 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.

Qualifications

• 5+ years of backend engineering with significant time spent building distributed systems in Go.
• Deep understanding of AuthN/AuthZ primitives: OAuth 2.0, OIDC, SAML, and JWT mechanics.
• Proven ability to manage complex data migrations, distributed architecture and build gRPC-based microservices.
• Exceptional written clarity; the ability to write Technical Design Documents (TPDs) that bridge the gap between India and US-based stakeholders.

Requirements

• You have previously been an early member of a distributed team and understand how to build culture across time zones.
• You treat "Zero-Trust" as a default, not a buzzword, and have experience with Zanzibar-style authorization or SpiceDB.
• You don't just ship code; you ship alerts, dashboards, and runbooks (and you have a "stop-and-fix" mentality).

Benefits

• Employment with Weave is contingent upon the successful completion of a background check, conducted in accordance with applicable laws.
• We use Artificial Intelligence (AI) tools to help us work more efficiently and create a smoother candidate experience.
• We are committed to fostering an inclusive workplace where all individuals are valued and supported.
• We welcome anyone who is hungry to learn, problem-solve and progress regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity, veteran status, or other applicable legally protected characteristics.
• If you have a disability or special need that requires accommodation, please let us know.
• Beware of recruitment fraud. All official correspondence will occur through Weave branded email.
