About the role
About the company
Our client is a fast-growing software company.
The role
Raydar is recruiting for this role on behalf of our client. Lead the technical direction of an AI-driven conversational product, shaping architecture, model selection and how quality is measured. Deliver production features across the stack while collaborating closely with early users and engineering leadership.
What you'll do
- Build the reasoning, tool-calling and memory layers of an AI agent, including graceful recovery when live interactions go off script within strict latency budgets.
- Create evaluation pipelines and data workflows that convert real conversation logs into steady, measurable gains, adding fine-tuning where it pays off.
- Strengthen the dependability of browser-based automation that runs during live sessions.
- Deliver full-stack features using TypeScript and Node.js.
- Partner with early customers to refine the product based on their feedback.
- Choose which models and techniques to adopt, weigh build versus buy decisions, and plan the next set of capabilities.
Requirements
What we're looking for
- Around 3 to 7 years of engineering experience, with a track record of taking AI agents from concept through to production.
- Prior hands-on work at a company in conversational AI, AI-driven sales, browser agents or a comparable fast-moving AI area.
- A minimum of one year working on low-latency, streaming or live audio systems.
- Background building interactive, real-time software or automation agents.
- Accountability for the whole agent lifecycle, including quality evaluation, monitoring and cost control.
- Strong command of modern JavaScript-based web development, especially TypeScript and Node.js.
- A computer science degree is preferred, though candidates from math, physics, engineering or other technical backgrounds are welcome.
Bonus points
- Familiarity with browser automation tooling.
- Past experience as a startup founder or founding engineer.
- An entrepreneurial mindset.
