Note: The job is a remote job and is open to candidates in USA. Navii is working with an established connected-fitness company to help them hire a Senior Software Engineer, Data Services. In this role, you will own the backend systems that turn every workout into trusted member activity and provide real-time insights, while also contributing to the development of an AI coach that adapts on the equipment.
Responsibilities
- Own the systems behind member activity end-to-end — telemetry ingestion, activity aggregation, streaming pipelines, third-party integrations, and the APIs that power the experience across mobile apps and connected equipment
- Ship the backend for an AI coach — the data plumbing behind adaptive workout plans: right data, low latency, dependable delivery
- Turn raw telemetry into insight — pipelines that produce AI-generated summaries, trends, and progress members can feel
- Deliver data in real time, at scale — low-latency streaming systems where reliability isn't optional and milliseconds matter
- Modernize core pipelines & integrations — re-architecture that moves the platform to the next order of magnitude on cost, reliability, and maintainability
- Build AI into how the team works — find high-leverage places to use AI/LLMs to accelerate engineering
Skills
- Proven production ownership of backend services and data-intensive, event-driven systems (streaming, ingestion, time-series/aggregation, or high-throughput integrations)
- Strong backend fundamentals with Node.js and TypeScript, including solid API design and service architecture
- Hands-on AI development experience — building real features with modern AI tooling
- AWS + infrastructure-as-code experience (Lambda/Serverless, ECS Fargate, MSK/Kafka or Kinesis, RDS/Postgres, MongoDB, S3, Terraform)
- A reliability mindset — SLOs, observability, alerting, and driving down recurring incidents
- Experience with high-scale streaming/messaging (Kafka/MSK, Kinesis) and time-series or aggregation workloads
- Experience re-architecting legacy pipelines for cost and reliability
Benefits
- Remote (US)
