• Engineer distributed ingestion services that reliably pull data from diverse sources, handle messy real-world edge cases, and deliver clean, well-structured outputs to multiple downstream products. • Build high-throughput processing components (batch and/or near-real-time) with a focus on performance, scalability, and predictable cost, using strong profiling and measurement practices. • Design and evolve data contracts (schemas, validation rules, versioning, backward compatibility) so downstream teams can build with confidence. • Own production quality: write maintainable code, strong unit/integration tests, and add the observability you need (metrics/logs/tracing) to diagnose issues quickly. • Improve platform reliability by hardening pipelines against partial failures, retries, rate limits, data drift, and infrastructure issues—then codify those learnings into better tooling and guardrails. • Contribute to CI/CD and developer experience: faster builds, better test signal, safer releases, and automated operational checks. • Participate in design reviews, code reviews, incident retrospectives, and iterative delivery—making pragmatic trade-offs and documenting them clearly.

The Company Rational Dynamics builds customized AI reasoning systems for tasks of high cognitive complexity. 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. Job Opportunities We are looking for entrepreneurial researchers and engineers who want to work on cutting-edge agentic AI methods and build out a best-in-class core technical infrastructure. Our work environment is highly collaborative. Your colleagues will be accomplished experts in AI/ML, statistics, and systems engineering. Job Description As a Forward Deployed Engineer, you will implement AI systems for leading institutions. You will work closely with clients to understand their unique needs, partnering with RD researchers to build end-to-end workflows. You will manage deployments in cutting-edge cloud and data environments. You will contribute to architectural decisions and product roadmaps. Duties Collaborate with customers and researchers to thoroughly understand business objectives and technical constraints Lead the technical implementation of customized large reasoning models and related AI systems, including prototyping, deployment, and monitoring Deliver high-quality code and documentations meeting the highest engineering standards Continuously improve the RD system design and deployment process Provide targeted training to clients, including non-technical stakeholders Preferred qualifications Skill in building LLM systems and familiarity with agentic workflows Foundational knowledge of AI/ML, especially modern generative AI Skill in deploying systems across multiple cloud platforms (GCP, AWS, Azure, neoclouds, hybrid) and data architectures “Friends of Rational Dynamics” Candidate Referral Program If you have a great candidate in mind for this role and would like to have the potential to earn $7,500 to $15,000 if your referred candidate is successfully hired and employed by Rational Dynamics, please use this form to submit your referral.
