About Rivian Rivian is on a mission to keep the world adventurous forever. This goes for the emissions-free Electric Adventure Vehicles we build, and the curious, courageous souls we seek to attract. As a company, we constantly challenge what’s possible, never simply accepting what has always been done. We reframe old problems, seek new solutions and operate comfortably in areas that are unknown. Our backgrounds are diverse, but our team shares a love of the outdoors and a desire to protect it for future generations. Role Summary Rivian's Identity Platform team builds the core systems that power authentication, authorization, and user lifecycle management across every customer-facing product Rivian ships — mobile, web, and vehicle software. We are seeking a Senior Software Engineer to join a newly formed Serbia-based team and be a core contributor to one of the most critical infrastructure platforms in our stack. In this role, you will own backend services end-to-end, operate them in production, and work closely with a Staff Engineer and Principal Architect to evolve a high-scale, high-availability identity platform that serves millions of Rivian customers. Responsibilities Backend Service Development: Design, implement, and maintain scalable backend microservices. Own features from design through implementation, testing, and production operation. Authentication & Authorization: Build and evolve the identity primitives that protect Rivian's customer products — including token issuance and validation, OAuth2/OIDC flows, MFA delivery, session management, and access control enforcement. Cloud Infrastructure: Build and maintain infrastructure-as-code for cloud-managed resources including databases, caches, message queues, and event streaming services. Event-Driven Systems: Design and maintain event-driven workflows integrating the identity platform with partner systems across the broader platform ecosystem. Observability & Reliability: Own production health of the services you build. Write structured logs, define metrics, author runbooks, and participate in on-call rotation. Technical Leadership: Participate in code review, contribute to engineering standards, and mentor mid-level engineers. Document design decisions and operational procedures to keep the platform understandable and maintainable. Cross-Functional Collaboration: Partner with Security, Product, Data Privacy, and Infrastructure teams that depend on the identity platform. Translate cross-functional requirements into well-designed technical solutions. Qualifications Bachelor's or Master's degree in Computer Science or a related field. 5+ years of professional backend software engineering experience. Strong proficiency in at least one backend language (e.g. Python, Go, Java, Node.js) and comfort picking up new ones. Solid understanding of REST API design, HTTP fundamentals, and service-to-service communication patterns. Hands-on experience with cloud services — databases, queues, caches, and serverless compute (e.g. AWS, GCP, or Azure equivalents). Experience deploying and operating services on container orchestration platforms such as Kubernetes. Solid understanding of authentication and authorization concepts: session management, tokens, MFA, and OAuth2/OIDC fundamentals. Strong debugging and observability skills — structured logging, metrics, and distributed tracing. Excellent written and verbal English communication skills. Nice to have Experience with infrastructure-as-code tooling (e.g. Terraform, Pulumi, or similar). Familiarity with async task processing and message-driven architectures. Experience building customer identity or IAM platforms at scale. Familiarity with fine-grained authorization concepts (e.g. ReBAC, ABAC, policy-based access control). Familiarity with privacy-aware system design and the engineering implications of GDPR or CCPA. Background in automotive, IoT, or connected consumer product companies.
