Software Engineer – Systems & Reliability

Smallest.ai | Bangalore

About The Role

Own a service or a part of our product from design through production. You’ll write the code, validate its behaviour, deploy it and keep it reliable for the customers who depend on it.

Testing, deployment and operations are part of engineering ownership here. You’ll work with the team, but you won’t hand off responsibility when your code is merged.

Our systems power real-time voice, where an extra 100 milliseconds can change how a conversation feels. Behind that experience are GPU inference workloads for text-to-speech and speech recognition across AWS regions, alongside multi-tenant APIs, concurrency controls, billing and webhooks.

We work with Python, TypeScript and Go on Kubernetes in AWS, supported by Redis, MongoDB-compatible stores, Postgres, ClickHouse, RabbitMQ and Temporal. Familiarity helps; understanding the mechanisms underneath matters more.

What you’ll own
