Engineering Leader

The Company

Rational Dynamics builds customized AI reasoning systems for high-cognitive-complexity work, beginning with institutional finance.

Our initial market is the world’s leading institutional asset owners. We work very closely with these customers to create specialized, rigorous benchmark datasets encompassing their most valuable and difficult knowledge work. Then we use the benchmarks to construct agentic large reasoning models, applying the same rigor to prove that the models correctly do the work. Customers access the models through a tailored application service, making their most skilled, expensive workers dramatically more productive.

We are an early-stage startup. Our founders previously started Voleon, now one of the world’s largest systematic investment managers, and recognized as a longstanding industry leader in applied machine learning. They bring to Rational Dynamics the same research discipline and data-driven focus that succeeded in the unforgiving, high‑stakes setting of financial markets.

We are hiring a Senior Manager of Engineering to lead a multidisciplinary team of engineers and scientists building agentic AI systems that work in real enterprise environments.

This is not a pure people‑management role. The right person thinks like a founder: they care about customers, product, technical architecture, velocity, team health, and code in the same week. You should have been hands‑on in agentic development and want to stay close to the work while leading a substantial team.

You will manage engineers and scientists building systems that combine LLMs, retrieval, agent orchestration, evaluation, data pipelines, customer‑specific workflows, and enterprise deployment constraints. You will help turn early customer needs and feedback into reliable, reusable platform capabilities while keeping the team focused on speed, rigor, and customer delight.

• Lead, coach, and scale a high‑performing team of engineers and scientists; initially as a line manager, with scope to manage managers as the organization grows
• Own delivery of agentic AI systems from ambiguous customer need through prototype, production deployment, evaluation, and iteration
• Stay technically hands‑on through architecture reviews, build/buy decisions, agentic workflow design, eval strategy, and urgent customer‑critical problem solving
• Partner with the Director of Product, Director of UX, and customer‑facing teams to translate customer workflows into clear technical roadmaps
• Build operating mechanisms that help the team move fast without unnecessary process: crisp priorities, clear ownership, fast feedback loops, and disciplined execution
• Raise the engineering bar for reliability, observability, security, compliance, and deployment quality in high‑consequence enterprise environments
• Recruit, develop, and retain exceptional technical talent; create a culture where engineers and scientists do their best work
• Model RD’s tenets: continuously delight customers, remove bottlenecks, disagree and commit, take ownership of every problem, prototype rapidly, and stay at the leading edge

• Significant experience leading engineering teams that ship production software in complex, ambiguous environments
• Demonstrated ability to manage strong technical ICs, including engineers and/or applied scientists
• Hands‑on experience building with modern AI systems, such as: agents, RAG, tool use, workflow orchestration, evaluations, LLM applications, or adjacent systems
• Strong product and customer judgment: you can identify what customers truly need, not just what they initially ask for
• Enterprise‑grade engineering instincts, including security, data boundaries, observability, deployment, and operational reliability
• Founder‑like ownership: high agency, low ego, bias for action, comfort with ambiguity, and willingness to take on whatever matters most
• Clear communication and strong judgment under pressure; able to debate hard, align quickly, and execute

• Experience at an early‑stage startup or as an early technical leader scaling a product from 0→1 or 1→N
• Experience managing managers or building the…
