Job
Description
As an experienced Backend Engineer, you will be responsible for owning the backend architecture and delivery process of an edge-to-cloud video AI platform. You will lead a small team in designing and shipping secure, observable, low-latency services in Rails. Your work will involve extending an active codebase, improving latency and reliability, and introducing new features regularly. **Key Responsibilities:** - Service Architecture: Design and maintain API gateway, Rails API services, background workers, and websockets. - Data Plane: Implement durable eventing, queues, back-pressure mechanisms, and ensure exactly-once processing where necessary. - AuthN/Z and Policy: Manage authentication and authorization using JWT, mTLS, RBAC/ABAC, and OPA/Rego policy checks. - Data Stores and Models: Design PostgreSQL schemas, handle partitioning, migrations, and indexing for efficient data storage. - Caching and Realtime: Utilize Redis for cache/pubsub, implement ActionCable or alternative WebSocket hubs for real-time data handling. - Integrations: Develop REST/XML adapters for external agencies and enterprise systems. - Observability: Set up metrics, logs, traces, dashboards, and SLO burn alerts for effective monitoring. - CI/CD and Environments: Establish build pipelines, artifact signing procedures, staged releases, and rollbacks for streamlined deployment. - Reliability: Manage incident response, on-call rotation, postmortems, and runbooks to ensure system reliability. **Core Responsibilities:** - Design and deploy Rails API-only services with clear boundaries and idempotent endpoints. - Define protobuf/JSON schemas for events and external adapters, ensuring version control. - Implement event streaming (Kafka or NATS JetStream) and Dead Letter Queues (DLQs). - Develop background jobs (Sidekiq) and scheduled workflows with retries and circuit breakers. - Enforce security measures like secrets management, mTLS, request signing, rate limiting, and audit logging. - Ensure data retention and privacy controls for media and Personally Identifiable Information (PII). - Lead code reviews, pair programming sessions, and contribute to the technical roadmap of the project. **Qualifications Required:** - 6+ years of experience in building production backends, with at least 3 years working with Rails at scale. - Proven expertise in designing multi-service systems with queues/streams and strong data modeling skills. - In-depth knowledge of PostgreSQL performance optimization, including query plans, indexes, partitions, and migration strategies. - Experience in secure API design, real-time data delivery, observability, and leading teams in a fast-paced environment.
