Descrição da Vaga
Who We Are Seeking:
We're looking for a talented and experienced Elixir Backend Developer to join our international team and help design, build, and harden our agentic contracts execution layer—the platform where autonomous/agent-driven workflows orchestrate and execute contractual logic reliably, at scale. This role presents an excellent opportunity for those looking to work in a dynamic environment and be part of a high-performing international team, offering ample opportunities for growth and development in technical and interpersonal skills. You'll work on resilient OTP services, job orchestration, stateful workflows, and observability to ensure correctness, auditability, and performance. We seek an energetic, driven, and articulate team player who is truly passionate about their work
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).
