Job Description
Overview
HiringAgents.ai, a Braintrust client, is actively building AI-native, production-grade agentic systems for talent acquisition. They operate live AI agents that interact with thousands of users semi-autonomously in real production environments.
They are seeking a senior contractor to significantly enhance feature delivery, increase engineering throughput, and contribute directly to AI agent systems currently in production. This is a high-impact, execution-focused role where you will collaborate directly with the founder and core engineering team.
What You Will Do
- Build and ship features across an AI-native product stack
- Design, implement, and improve agentic systems powered by LLMs
- Work with production AI agents handling real user interactions at scale
- Contribute across backend and frontend where needed
- Collaborate closely with product and engineering to move fast from idea to production
- Leverage AI-assisted development workflows to maximize velocity
Technical Stack
- TypeScript across the stack
- React Native for frontend
- Deno for backend runtime
- Vercel for deployment
- LLMs and agent frameworks in production
- Modern observability and logging (for example Sentry)
- AI-native development workflows (Claude, GPT, copilots, etc.)
What We Are Looking For
- Senior engineer with strong hands-on experience (at least 5 years of experience)
- Prior experience deploying LLM-powered systems or agents into production
- Comfortable working in fast-moving, ambiguous environments
- Strong TypeScript experience
- Experience with modern cloud and serverless environments
- Pragmatic mindset, focused on shipping, not over-engineering
- Actively embraces AI-assisted coding and tooling
- Not interested in purely manual, anti-AI development approaches
Nice to Have
- Experience with agent orchestration patterns
- Experience building systems that operate autonomously or semi-autonomously
- Background in startups or high-velocity product teams
Contract Details
- Contract role
- Initial engagement expected to be full-time
- Target start as soon as possible
- Longer-term extension very likely if the collaboration is successful
- Flexible duration, typically mid to long term engagements
Why This Role
You will be working on real, production AI systems that reflect where the industry is heading, not experiments or prototypes. This is an opportunity to build the future of AI-native software with immediate real-world impact.
