Senior Backend Engineer – Users Infrastructure

Job description

Accountabilities: Architect and develop core services responsible for the identity lifecycle, authenticating both human and machine identities across the platform. Design and evolve modern Identity and Access Management (IAM) capabilities, including authentication, authorization, session management, and identity data consistency. Define and implement fine-grained authorization models across complex, multi-tenant organizational and location hierarchies. Lead the transition from legacy authorization approaches toward modern, scalable authorization infrastructure using SpiceDB and Zanzibar-style permission models. Build and maintain the internal SDKs, gRPC contracts, middleware, and developer tooling that provide secure, standardized integration patterns for downstream engineering teams. Establish and maintain enterprise identity integration standards, including SSO, federated identity, SCIM provisioning, and secure machine-to-machine communication. Design and execute complex data migrations and distributed-system changes while maintaining reliability, consistency, and security. Improve operational excellence across Tier-1 services by strengthening observability, monitoring, load testing, alerting, MTTD, and MTTR practices. Own the reliability and integrity of audit logging pipelines and identity data as trusted sources of truth. Develop technical documentation, including detailed Technical Design Documents, to align stakeholders across India and the US. Establish strong engineering standards, operational practices, and a collaborative culture for the growing India-based team. Mentor and support engineers while contributing hands-on to architecture, implementation, code reviews, incident response, and technical strategy. Work asynchronously and collaboratively with distributed engineering, product, and infrastructure teams across multiple time zones. Requirements: 5+ years of backend software engineering experience, with substantial experience building distributed systems in Go. Strong understanding of identity and security fundamentals, including OAuth 2.0, OpenID Connect (OIDC), SAML, and JWT. Proven experience designing and operating distributed architectures and backend services at scale. Experience designing and implementing gRPC-based microservices and service-to-service communication. Demonstrated ability to plan and execute complex data migrations while maintaining system reliability and data integrity. Strong understanding of secure software engineering principles and a Zero-Trust security mindset. Exceptional written communication skills, with the ability to produce clear technical design documents and communicate complex architectural decisions across distributed teams. Ability to work independently, take ownership of ambiguous technical challenges, and make sound architectural decisions. Experience working effectively across geographically distributed teams and time zones. Preferred qualifications: Previous experience as an early or founding member of a distributed engineering team or regional technology hub. Hands-on experience with SpiceDB, Zanzibar-style authorization, or comparable fine-grained authorization systems. Experience designing identity and access management platforms or security-critical backend infrastructure. Strong focus on reliability engineering, including dashboards, alerts, runbooks, load testing, incident response, and proactive system improvement. Experience establishing engineering standards, operational practices, and technical culture within a growing team. Strong ability to balance hands-on engineering with technical leadership and cross-functional influence. Benefits: Fully remote position based in India. Opportunity to become a founding member of a new regional infrastructure engineering team. High degree of technical ownership over foundational identity, authorization, and security systems. Opportunity to work with modern technologies including Go, SpiceDB, gRPC, distributed systems, IAM, and cloud-scale infrastructure. Exposure to complex security, reliability, and enterprise identity challenges. Opportunity to collaborate with a globally distributed engineering organization across India and the US. Significant scope for technical leadership, architecture ownership, mentorship, and professional growth. Opportunity to establish engineering standards and culture for a growing regional team. Inclusive, equal-opportunity work environment focused on learning, problem-solving, and career development. Employment is subject to successful completion of a background check in accordance with applicable laws.
