Lead Backend Software Engineer, Distributed Systems

Job Description

Terality's stack: Python, Pandas & Numpy, Parquet…
Terality's infrastructure: AWS, Redis, Datadog, GitLab…

Your main mission will be to develop and scale Terality's core product: a distributed data processing engine.
From the start, you will help deploying hundreds of workers per second and using major cloud providers services at a rate reaching their limits, and all of this like clockwork.
You will find the right mix of serverless and server technologies to help us scale from processing a few GB/s to a TB/s, with instant auto-scaling.

You will be regularly challenged and learn new technologies to deal with our unique technology! What's more, you will have a direct and immediate impact on Terality's users.

Terality's core product involves a client-side Python library talking through a JSON REST API to a scheduler service, which transforms client requests into parallel computation tasks, slices and dices the data, schedules and runs the tasks on a pool of workers, and returns the results to the client.

Secondary tasks will include anything else that makes a robust and scalable API: persistence and durability of data, performance, availability, reliability, security, monitoring, analytics…

Joining us will make you an expert at advanced data processing!
