Backend Software Engineer — Data Platform & AI Data Products

6+ years building production backend systems (distributed systems, APIs, data services).

Strong skills in at least one backend language (e.g., Go, Python, Java, Rust) and API design (REST/gRPC).

Demonstrated ability to own services end-to-end: design docs, implementation, testing, deployment, on-call, and iteration based on real usage.

Strong engineering fundamentals: clean, maintainable code, thoughtful abstractions, strong design patterns, and systems that are easy to evolve.

Solid data modeling and query skills (SQL) and experience with at least one of:

Streaming/eventing (Kafka/PubSub/Kinesis, etc.)

We offer competitive compensation, startup equity, health insurance and other competitive benefits. The US base salary range for this full-time position is: $160,000 - $240,000 + equity + benefits. Our salary ranges are determined by location, level and role. Individual compensation will be determined by experience, skills, and job-related knowledge.

You’ll join the Data Platform team, responsible for building the backend services and “data products” that power how data moves through the company. We create the core platform primitives - high-quality event streams, reliable access layers, and developer-friendly APIs/tools - so teams across the org can self-serve what they need and ship faster. You’ll design, build, and run backend services that create value from our company data, and make our data platform more self-serve (DIY)- so product and engineering teams can easily create and operate event-driven architectures, publish/consume streams, define access models, and ship data products end-to-end. You’ll also build LLM-adjacent services such as prompt categorization/taxonomy, enrichment, and metadata systems that turn raw telemetry into trusted, usable products.

Identify, design, and develop foundational data infrastructure components capable of handling millions or billions of events daily

Analyze and improve the robustness and scalability of existing data processing infrastructure

Partner with product teams to understand functional requirements and deliver solutions that meet business needs

Write clear, well-tested, and maintainable infra-as-code and software for both new and existing systems
