Most backend systems look fine on paper until they hit production.

This role is about building services that actually work at scale, under real user demand.

Why This Role
  • Leading major media/streaming end client
  • Real production impact from day one
  • Solving practical backend challenges in a high‑scale environment
The Company / Product

You’ll be working on a large‑scale platform used by millions, helping build and support backend services that power critical parts of a streaming ecosystem.

What You’ll Be Working On
  • Building and supporting APIs and microservices in production
  • Developing backend systems using Python + AWS (Lambda, API Gateway, S3, Dynamo

    DB)
  • Working with event‑driven systems (Kafka, SNS/SQS, etc.)
  • Supporting and improving existing production systems
  • Debugging real‑world issues and keeping systems stable at scale
  • Collaborating within an existing team + codebase (pragmatic engineering)
  • Python
  • AWS (Lambda, API Gateway, S3, Dynamo

    DB, IAM)
  • Observability (Prometheus, Grafana, Cloud Watch)
What You’ll Bring
  • Experience building and supporting microservices in production
  • Good understanding of event‑driven architectures
  • Ability to debug and support live systems effectively
  • Comfortable working in fast‑moving teams with minimal hand‑holding
Ideal Profiles
  • Mid‑Senior Backend Engineers with strong production exposure
  • Engineers used to working in existing systems (not just greenfield)
  • Profiles from streaming, SaaS, or high‑traffic platforms

(This is not a pure greenfield build - it's about making real systems better and keeping them running)
