The Role

We are helping to hire a Senior Software Engineer to strengthen the core foundation of our agentic data analytics platform, ensuring reliability, scalability, and performance as we move from MVP to enterprise scale.

This is a core platform role with real ownership. You will work on data integrations, platform execution, and the systems that power AI-driven analytics.

What You Will Be Doing
  • Building core data integrations with common SaaS platforms
  • Designing data pipelines that ingest provider APIs into our analytics datastore
  • Improving the agent platform and executor with better error handling, observability, and speed
  • Making LLM interactions more efficient through prompts, snippets, and tooling
  • Improving internal developer experience and platform tooling
  • Helping take an early MVP into a production-grade platform
Why Join
  • Early, high‑impact role in an AI‑native company
  • Direct influence on platform architecture and technical direction
  • Opportunity to work with an experienced founding team
  • Build technology that fundamentally changes how teams use data
The Stack
  • Go (Railway)
  • Terraform (Infrastructure as Code)
What We Are Looking For
  • 3+ years of Go experience
  • Deep understanding of design patterns and system architecture
  • Experience building scalable, performant platforms
  • Strong grasp of event‑driven systems and concurrency
  • Solid database and API design experience, ideally with Postgres
  • Understanding of good security practices
  • Ability to clearly communicate technical trade‑offs
  • Familiarity with the modern AI tooling landscape
  • Some cloud infrastructure experience including Terraform
Nice to Have
  • Zero‑to‑one product experience, including OSS or side projects
  • Data engineering experience such as pipelines and analytics
  • Experience integrating LLMs, including prompt design and understanding model capabilities
  • Deeper cloud experience, especially with GCP
  • Experience with Encore, though this is easy to pick up
Ways of Working
  • Ownership mindset with comfort taking ideas from rough outline to implementation
  • Execution first approach where speed matters, balanced with pragmatism
  • Iterative development focused on shipping, learning, and improving
  • First‑principles thinking rather than cargo‑cult engineering
  • Ego‑less culture with direct, constructive feedback
  • Comfort working asynchronously and learning independently
  • AI‑native approach using tools like Cursor or Claude Code to move faster
