Job Title: Backend / Data Engineer

Location Type: Remote Employment Type: Full-Time

About Sleeper

Sleeper is a rapidly growing platform for sports fans with messaging and gameplay at its core. While much of our stack is Elixir-driven, this role bridges Python data services with our Elixir backend, GCP, and distributed analytics stores. You’ll own the data plumbing that powers real-time pricing, risk analytics, and settlement while collaborating across product, data-science, and trading teams.

What You’ll Be Doing

• Design & implement real-time data pipelines (Python, SQLX, BigQuery) that ingest odds, bets, and exposure signals with low latency.
• Build and operate backend micro-services for pricing, settlement, and limit management that expose clean gRPC/REST contracts to our Elixir cluster.
• Architect a feature store that serves models in production and supports ad-hoc analytics with strong data governance.
• Integrate streaming & pub/sub systems (Kafka / Google Pub/Sub) with caching layers (Redis, ScyllaDB) to guarantee consistency under high throughput.
• Harden CI/CD, observability, and incident-response runbooks so data integrity issues surface before they hit users.
• Partner with data scientists to deploy and monitor models end-to-end, from training to online inference.
• Own projects from ideation through production, balancing delivery speed against the safety demands of real-money systems.

Who You Are

• 4+ years of backend and/or data-engineering experience with Python (FastAPI, Django, or similar) plus strong SQL chops.
• Proven track record designing distributed systems that handle high-volume, low-latency workloads.
• Experience with stream processing (Kafka, Pub/Sub, Flink or Beam) and warehouse technologies (BigQuery, Snowflake, or Redshift).
• Comfortable—or eager to learn—Elixir/Erlang and other functional stacks.
• Pragmatic engineer who anticipates edge cases and failure modes in financial or real-time environments.
• Calm, methodical communicator during incidents; you thrive under pressure.

Preferred Skills (Nice to Have)

• Prior work with ScyllaDB/Cassandra, ClickHouse, or other wide-column / OLAP stores.
• Hands-on experience with Kubernetes, Terraform, GitLab CI, and observability stacks (Prometheus, Grafana, OpenTelemetry).
• Familiarity with Rust, Go, or C++ for ultra-low-latency components.
• Knowledge of risk modeling, market-making algorithms, or sports-betting infrastructure.

Benefits

• Competitive salary and stock options
• Comprehensive health, dental, and vision insurance
• 401(k)
• Flexible working hours and remote-first culture
• Clear paths for career growth and leadership
