Elixir Backend Developer

Who We Are Seeking Are you passionate about Elixir/OTP, distributed systems, and high performance? At DevGrid, we're looking for an Elixir Backend Developer to join our international team and help build the agentic contracts execution layer — the platform where autonomous/orchestrated workflows reliably execute contractual logic at scale. Here, you'll have the opportunity to work in a dynamic, collaborative, and innovative environment, developing resilient and scalable solutions with a strong focus on performance, auditability, and reliability. Your Role and Responsibilities Design and implement Elixir/OTP services (GenServer, Supervision trees, Registries) that power contract execution and agentic workflows. Own the lifecycle of long-running, event-driven workflows (timers, scheduling, compensations/Saga patterns, exactly-once/at-least-once semantics). Develop secure APIs and integrations, rate limiting, and request budgets for agent calls. Optimize performance (ETS, streams, batching, backpressure) and observability (tracing, metrics, structured logs). Collaborate with Product and AI/Agent teams to translate requirements into deterministic, testable contract execution flows. Write high-quality tests, migrations, and production-grade documentation. Tech You'll Use: Elixir/OTP (GenServer, Supervisors, Applications), Phoenix (APIs), Ecto (PostgreSQL), Oban, OpenTelemetry/PromEx Message brokers & streams: Kafka or RabbitMQ Container & cloud: Docker, Kubernetes, AWS/GCP/Azure CI/CD: GitHub Actions (or similar), feature flags, migrations & rollout strategies Essential Qualifications 3+ years building production Elixir/OTP services (or 5+ years BE + 1–2 years Elixir with strong OTP fundamentals). Deep understanding of concurrency, supervision strategies, and fault tolerance on the BEAM. Solid experience with Ecto/MySQL, schema design, transactions, and migrations. Practical knowledge of job orchestration (Oban or equivalent), idempotency, retries, and backpressure. Proven track record in building and maintaining event-driven or workflow systems with strong correctness guarantees. Comfortable with containerized deployments and CI/CD; you ship and you own. Strong written and spoken English (daily collaboration in English).
