About the role
- Design and implement scalable backend architectures for AI workloads (inference, orchestration, monitoring).
- Own distributed job orchestration with Temporal and related systems.
- Improve data pipeline performance by designing smarter caching strategies (e.g., file deduplication, hot/cold storage, Redis caching layers) to reduce redundant compute and API calls.
- Build observability, monitoring, retries, and fault tolerance into all workflows.
- Manage infrastructure reliability, incident response, and performance.
- Develop tooling and platform infrastructure to support rapid growth.
- Partner with ML engineers to bring models to production at scale.
Requirements
- 4+ years of backend engineering (Python is a must).
- Strong background in distributed systems, job orchestration, and task queues.
- Deep knowledge of concurrency, parallelism, and multithreading—including async/await, event loops, thread pools, synchronization primitives, deadlocks, and race conditions—is a must.
- Hands-on experience with Temporal, Redis, Airflow, Celery, RabbitMQ (or similar).
- Experience with LLM serving and routing fundamentals (rate limiting, streaming, load balancing, budgets).
- Comfortable with containers & orchestration: Docker, Kubernetes.
- Familiarity with cloud platforms (AWS/GCP) and IaC (Terraform).
- Experience with multiple storage systems: S3, Postgres, MongoDB, Redis, and Elasticsearch.
- Track record scaling systems in startups or fast-paced environments.
- Understanding of deploying, monitoring, and optimizing AI/ML systems in production with strong CI/CD practices.
