Build the core systems our AI depends on. We're hiring a founding backend/data engineer to build the data layer, sync pipelines, and agent APIs our AI depends on. You'll work directly with the founders and own major pieces of the architecture from day one.

Why Bond?

At Bond, we are building the world's first AI Chief of Staff. After speaking with over 2,000 executives, we identified a universal pain point: information fragmentation and overload. Even the best teams spend countless hours chasing updates, untangling loose threads, and sitting in status meetings, only to find the data they need is buried in a silo.

We're building a system that understands what's happening across a company and tells leaders what truly deserves their time. You don't just save a few hours. You change how companies operate. This is a new layer of infrastructure. Whoever solves this becomes the operating system for modern organizations. This is a generational engineering problem: massive data ingestion, state modeling, prioritization logic, real-time inference, and agentic action loops.

And nobody has cracked it.

Backed by Y Combinator, Fellows Fund, Goodwater Capital, and E14, we are building the intelligence layer that connects these dots automatically. We have raised our seed round and are now expanding our engineering team.

What You'll Do

Evolve the foundation: You will help us transform our data layer into a mature and battle-tested system. You will build pipelines to extract context from third-party tools and normalize it into a queryable organizational knowledge base.

Build "Agent-Ready" interfaces: You aren't just building APIs for a frontend; you are building tools for AI agents. You will abstract away the complexities of external platforms into reliable, clean interfaces that our AI agents can control autonomously.

Orchestrate async workflows: We use sleep-time compute cycles to analyze data when users aren't looking. You will manage the worker infrastructure that allows agents to plan cycles, execute sub-tasks, and sync data in the background.

Semantic search & RAG: You will ensure that as soon as data flows in, it is vector-embedded and ready for retrieval, keeping our AI's context window fresh.

Ship for the user: We don't optimize code just for the sake of code. You will build with a relentless focus on how the end-user experiences the product: speed, reliability, and magic.

Our Stack

We trust you can pick up new tools quickly, but here is what we are building with today:

• Backend: Python, FastAPI, ARQ

• Data: PostgreSQL, Qdrant

• Infra: AWS, Terraform, Docker, GitHub Actions

• Frontend: TypeScript, Next.js, Tailwind

Who You Are

3+ years of backend experience, or a proven history of "high slope" engineering with complex projects.

System thinker: You understand that "syncing data" isn't just about copying rows; it's about handling diffs, rate limits, and eventual consistency.

Pragmatic & low ego: You step up in incidents to unblock teammates. You believe the best idea wins, not the loudest voice.

Product mindset: You don't just write code; you build solutions. You have deep empathy for the user and optimize for the feeling of the final product, not just the cleanliness of the architecture.

Startup ready: You are autonomous, ownership-driven, and able to navigate ambiguity. You don't wait for a spec; you find the problem and solve it.

Global communicator: You are proactive and reliable, capable of coordinating effectively between our Ghent and our San Francisco presence.

Driven: You are ready to make this your life's work.

If you're looking for work-life balance, predictable routines, or a well-defined roadmap… this isn't your place. If you want to build something that outlives you, welcome home :)
