Senior Backend Engineer

EngineeringRemoteFull-timePosted 2 days ago

Own the services that route millions of customer conversations a month - from message ingestion to AI orchestration.

About the role

Engium powers customer conversations for thousands of small businesses across WhatsApp, voice, and web. As a Senior Backend Engineer you will own end-to-end services that ingest messages, run our 3-tier AI pipeline, and push responses back to customers - usually in under 800ms.

What you'll do

Design and ship async, multi-tenant services in Python (FastAPI) and PostgreSQL.
Own one of: conversation engine, integrations (Meta / Twilio / Exotel), or billing & usage.
Drive technical decisions: API shape, schema changes, performance budgets, on-call playbooks.
Pair with product and design to scope work that ships in days, not quarters.
Mentor mid-level engineers and review code with care.

O que procuramos

5+ years building production backend systems, ideally in Python or a similar typed-async stack.
Comfortable with Postgres at scale - query plans, indexes, migrations, and the occasional pg_stat dive.
Strong async / concurrency instincts. You know when to use a queue, when to use a lock, and when to do neither.
You write tests because they help you ship, not because someone told you to.
Clear written communicator. You can RFC an idea before you build it.

Bonus points

Experience with LLM-backed products (RAG, function calling, evals).
Worked on telephony or messaging providers (Twilio, Meta Cloud API, RCS).
Multi-tenant SaaS or platform-engineering background.
