Role Overview
An AI-native engineering org. Agents across coding, reviewing, QA, ops, support, scheduling. You'll help turn the company itself into an intelligent system.
- Speech-to-speech agents that feel like a person in the room. Interruptions, back-channels, noisy kitchens, hearing aids, thick accents, millisecond latency.
- Companions with long-term memory. Knows someone after six months the way a friend would.
- Assistants inside messaging, connecting families across cities and countries.
- Health biomarkers from conversation. Cognitive decline, mood, breathing, loneliness, with research partners at Wharton, Toronto, and Oxford.
- PhD-level audio in production. Speech enhancement, VAD, diarization, TTS tuned for older voices.
- An agentic browser: booking appointments and getting things done online through conversation, no wrestling with websites.
What We Need
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
A cracked, AI-native engineer. You use AI to multiply what you ship, and you've made yourself measurably faster with coding agents or your own setup.
- You've shipped something that runs on an LLM in production. Voice AI experience (real-time STT, TTS, speech-to-speech, telephony) is a big plus.
- You go above and beyond and can prove it: a side project with users, a repo people star, a hackathon you won, something you built over a weekend because you couldn't stop. Show us.
- High agency. If something is broken and nobody owns it, you own it now. You'd rather be wrong fast than wait for a spec.
- Product taste. You care how it looks and feels, not just whether it works.
- Low ego, kind, hard-working. No politics.
- You care about the mission: older adults ageing well at home, work that matters to real families.
What We Don't Care About
- Where you went to university, or whether you did. Show us what you've built.
- Where you live. Overlap with London hours matters more than your postcode.
- Gender, age, background, or anything else that isn't the work.

Founding Engineer Means Founding
You will be integral to whether Harmonica succeeds. That's literal, and it comes with the freedom to match.
- Set the engineering standards: how we test, review, deploy, and use agents as we grow.
- Shape the stack. A strong opinion backed by evidence changes how we build.
- Hire the team. You'll interview and help decide who joins after you.
- Own broadly today (voice, memory, messaging, biomarkers); take primary ownership of a major surface as we grow.
- Real equity and a real voice in product, engineering, and company decisions.
- You'll learn more here in one year than in three at a corporate. That's a promise.
