We are hiring a Full Stack AI Engineer to build production LLM applications: RAG-powered assistants, agent workflows, and internal AI applications with excellent UX. You will work on end-to-end features across React/TypeScript UI, backend APIs, and LLM orchestration on Amazon Bedrock, including Agents, prompt engineering, evaluation, and vector database integration techniques.
You will partner closely with teams across Multi-Asset Solutions, Investment Research, Investment Products, Accounting, Marketing, and Distribution to turn real investment and business needs into production-grade tools that improve decision-making, efficiency, and client outcomes.
You’ll build production AI applications that directly support investment decision-making and client outcomes. We operate like a small, high-ownership team: fast iteration, real accountability, and a clear line of sight from what you ship to how the business invests and serves clients. You’ll collaborate closely with portfolio managers, quantitative analysts, and engineers, with the freedom to experiment and influence technical direction without getting trapped by legacy systems or slow, layered hierarchies.
This role is ideal for engineers who enjoy building AI powered software systems rather than developing standalone models. If your passion is designing and shipping LLM based applications such as retrieval augmented systems, agent workflows, and production grade AI services, you will thrive here.
You should be comfortable owning features end to end, including contributing to front end components when needed to improve usability, workflow design, and overall user experience. We value engineers who think in terms of complete solutions, not just backend services. Our emphasis is on building reliable, scalable applications that apply LLMs to real business workflows.
The ideal candidate will have knowledge and experience in one or more of the following areas which are essential to be effective and successful in this role:
Strong software engineering fundamentals with production experience in TypeScript/React and/or Python/FastAPI, (bonus: AI/chat/workflow UX, streaming responses).
Hands-on experience shipping LLM applications into production.
Experience designing RAG pipelines end-to-end: ingestion (parsing, chunking, embedding), retrieval (vector DB + filters), reranking, grounding/citations, and continuous evaluation.
Experience using LLM coding tool like Claude Code, OpenAI Codex or GitHub Copilot.
Experience designing and developing MCP and applications using agentic workflows.
Strong SQL and experience with Postgres/Aurora or similar.
Experience with Amazon Bedrock (models, guardrails, deployments, cost/latency tradeoffs).
Experience building multi-agent systems using agentic frameworks (tools, workflows, evaluations, observability)
Experience implementing vector database retrieval patterns (pgvector/OpenSearch/Pinecone/etc.)
Experience integrating OAuth2/OIDC for secure authentication/authorization (SSO, token flows, RBAC).
AWS experience (infrastructure, observability, CI/CD).
Nice to Have:
Kubernetes/EKS and IaC (CloudFormation/Pulumi).
Experience in regulated environments: auditability, PII handling, data entitlements.
Exposure to data governance and security practices in cloud environments.
Applies emerging AI/LLM capabilities pragmatically, with curiosity and good judgment.
Comfortable with discovery work: prototype, test, iterate, and validate before scaling.
Adapts quickly as requirements and technical approaches evolve.
Owns delivery end-to-end, driving work through production and refinement.
Communicates openly, contributes to design discussions, and challenges assumptions constructively.
Collaborates across teams and works across the stack when needed
Bachelor’s or Master’s degree in Computer Science, Engineering, Information Systems, or a related technical field. Degrees in Mathematics, Statistics, Economics, or similar quantitative disciplines are also welcome.
3 to 6 years of experience in Software Engineering, AI Engineering, Full Stack Engineering, Data Engineering, or related fields.
Demonstrated experience shipping production LLM applications (regardless of years).
Financial services industry experience is a plus but not required.
Relevant professional or technical certifications are a plus.
Compensation Pay Range: $150,000 - $165,000
This position is a hybrid opportunity based in our Chicago office. #LI-Hybrid
We’re an asset manager focused on curating an intentionally select suite of active ETFs that we believe have the potential to produce compelling, risk-adjusted returns within a portfolio. The next great solution can come from anywhere, and we’re passionately obsessed with the thrill of the chase. So, we aim to push boundaries and blaze trails. Our pursuit of excellence knows no bounds.
Unconstrained by geography and uncompromising in our due diligence, we scour the globe to find boutique partners with bold solutions. The hidden gems you’re unlikely to find anywhere else. The masters of their craft. The true artisans. The innovative thinkers who are exceptional at what they do and leaders in their distinct areas of focus. There aren’t many of them. But we’re always looking, always learning, always improving.
We seek to analyze from every angle, driven by an intense curiosity to understand what challenges advisors and how we can help them. We’re perpetual ponderers, non-stop thinkers, and market fanatics. The advisors who work with us are too. And we don’t just want to earn their trust – we want to keep it. That means sourcing solutions in an effort to outperform peers, working together to navigate market and product complexity, and digging into research with those who share our fervor for details.
As a manager of managers for most of our products, our independence enables a level of objectivity that we believe few others share. We're only biased when it comes to quality, so we can make swift decisions about who we partner with and what we recommend.
We love what we do, and the magic of success is something we want to share with our clients – and their clients.
