Job Title: AI Engineer (Full‑Time, On‑site / Hybrid) – Ghent, Belgium
Salary: $100k – 140k per year + 0.50 % – 1 % equity.
We're hiring an AI engineer to build the intelligence that powers Bond's AI Chief of Staff — the agents, briefing pipelines, prompt systems, and LLM infrastructure that turn raw company data into executive‑ready insight. You'll work directly with the founders and own our entire AI layer 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. 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. No one has cracked it yet.
Backed by Y Combinator, Fellows Fund, Goodwater Capital, and E14, we have raised our seed round and are now expanding our engineering team.
What You'll Do
Build agentic systems that actually work: You will own BondBot, our conversational AI agent. Today it orchestrates 30+ skillsets across 15 platforms — searching Slack threads, triaging Linear issues, drafting replies, managing todos — all through natural language. You will push this from "useful assistant" to "indispensable Chief of Staff" by improving tool orchestration, multi‑turn reasoning, and autonomous action loops.
Ship the daily briefing pipeline: Every morning, Bond generates a personalized executive briefing by running five specialized AI agents in parallel — extracting todos, summarizing updates, prepping meetings, tracking objectives, and surfacing what matters. You will own this pipeline end‑to‑end: the preprocessing, the agent orchestration, the prompt engineering, and the output quality.
Engineer prompts like software: We treat LLM prompts as production code. You will maintain our library of 80+ prompt templates with semantic versioning, structured output schemas, and a rigorous TDD evaluation loop (write failing tests first, then fix the prompt). You will know when a prompt is overfitting versus genuinely improving.
Orchestrate multi‑provider LLM infrastructure: Bond runs across OpenAI, Anthropic, Google, and AWS Bedrock with intelligent fallback chains, rate limiting, and circuit breakers. You will optimize for cost, latency, and quality — picking the right model for each of our 49+ generation functions.
Close the feedback loop: Great AI isn’t just about generation — it’s about measurement. You will build and maintain our evaluation framework, trace every LLM call through Langfuse, and turn qualitative feedback into quantitative pass rates that guide prompt iteration.
Our Stack
AI/LLM: LangChain, LangGraph, OpenAI, Anthropic, Google Gemini, AWS Bedrock
Backend: Python, FastAPI, ARQ, asyncio
Data: PostgreSQL, Qdrant, S3
Observability: Langfuse, Sentry, PostHog
Infra: AWS, Terraform, Docker, GitHub Actions
Who You Are
3+ years building LLM‑powered applications in production, or a proven history of "high slope" engineering.
Prompt engineer, not prompt gambler: You understand structured generation, tool calling, and output validation. You iterate on prompts with data, not vibes.
Agent builder: You have experience with agentic architectures — tool orchestration, multi‑step reasoning, memory management, graceful failure.
Async‑native Python developer: You are comfortable with asyncio, concurrent pipelines, and run five LLM‑backed agents in parallel without corrupting shared state.
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 optimize F1 scores; you optimize for the feeling of opening your briefing at 7 am and knowing exactly what deserves your attention.
Startup ready: You are autonomous, ownership‑driven, and able to navigate ambiguity.
Global communicator: You are proactive and reliable, coordinating between our Ghent and San Francisco presence.
Driven: You are ready to make this your life's work.
The Bond Offer
Location: Ghent, Belgium (office in Wintercircus); frequent travel to San Francisco.
Compensation: $100k – 140k per year plus 0.50 % – 1 % equity.
Benefits: competitive pay for Belgian market and a broad range of company benefits.
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.
