HERES WHAT YOULL DO
About the Role:
- Client is building an AI-native data visualization creative platform built to turn anyone into a confident data storytelling. Our app which is in the early alpha stages helps people go from raw data to compelling publication-quality charts without needing to be a data scientist or designer.
- Were a small fast-moving incubator team that ships production software and cares deeply about the craft. Were looking for a senior backend engineer with a strong AI systems background to help us build the intelligence layer that makes our service feel like it actually understands data.
- Youll work across our fluency engine composition pipeline and agentic infrastructure and have a direct hand in how the product reasons about data and communicates with users.
- Were a small team with real ownership. The problems are genuinely hard the feedback loop is short and the work ships to real users inside one of the largest creative platforms in the world.
What Youll Work On:
- Design and evolve our GraphQL API and the services behind it ( Postgres S3 Docker/Kubernetes)
- Build and improve AI-powered features: chart recommendation data fluency narrative generation and agentic workflows that act on user intent
- Own the eval infrastructure by defining what good looks like for our AI systems build LLM-as-judge pipelines and drive quality improvements from signal
- Work across our composer and fluency engines: the systems that translate user data and intent into visual output
- Contribute to architecture decisions: schema design data loading and processing patterns and pipeline orchestration
- Partner closely with frontend engineers and designers (who often work directly in the codebase) to ship full features end-to-end
Skills:
What Were Looking For:
- 6 years of backend engineering experience with strong TypeScript/ fundamentals
- Hands-on experience building with LLMs: prompt engineering structured outputs tool use retrieval caching strategies and cost/latency tradeoffs
- Experience with agentic architectures: multi-step reasoning tool-calling agents orchestration patterns and the failure modes that come with them
- You think carefully about eval infrastructure not just whether the model works today but how youd know if it regressed tomorrow
- You write code thats clear well-typed and doesnt require a comment to explain what it does. You are comfortable moving quickly and leveraging AI assistance. You can understand tradeoffs particularly when it comes to moving quickly and code quality.
Bonus Points:
- A genuine enthusiasm for data visualization. You find yourself opinionated about when to use a bar chart vs. a line chart and you know why it matters
- Experience with LangSmith LangFuse or similar LLM observability tooling
- Familiarity with React and willingness to read and occasionally contribute to frontend code
- Prior experience in a design-adjacent or creative tools product
Education: Tech We Use
- TypeScript GraphQL Apollo PostgreSQL Drizzle ORM Langchain Vercel Docker Kubernetes Nx monorepo React 19 Vite Vitest Storybook AWS Azure
BENEFITS:
We offer a comprehensive benefits package designed to support the health well-being and financial security of our employees and their families. Eligible employees may receive:
- Health Insurance: Medical dental and vision coverage
- Retirement Plans: Participation in a company-sponsored retirement savings plan.
