WHERE YOU’LL FIT WITHIN THE TEAM
Full-Stack TypeScript Engineer, AI Products build and deliver end-to-end AI product experiences across the PE due diligence ecosystem. This role sits at the intersection of product engineering and applied AI, combining solid full-stack software engineering with practical knowledge of how LLMs and agentic systems behave in production.
This role is TypeScript-first. Most of the analyst-facing product surfaces and Node.js services on the Workstream team are built in TypeScript, and we expect this engineer to own and extend that stack end-to-end. Python remains a strong co-requirement for the AI orchestration and pieces within our backend layer (LangGraph, FastAPI, agent services), so candidates must be comfortable working productively across both ecosystems even where TypeScript is their primary depth.
You will build intelligent product features from backend services through frontend experience, contributing to the workflows, orchestration layers, and user interfaces that make AI useful, reliable, and intuitive for end users. This includes implementing agent workflows, retrieval pipelines, evaluation gates, human-in-the-loop review patterns, and the analyst-facing experiences that surface them. You are technically strong in production AI systems and capable of translating non-deterministic model behavior into clear, trustworthy product experiences with guidance from senior engineers.
You will contribute to engineering standards, participate in code reviews, and grow your expertise in building safe, observable, and scalable AI-powered workflows.

ABOUT YOU
- Bachelor’s degree in Computer Science, Engineering, Information Systems, Data Science, or a related field, or equivalent practical experience.
- Demonstrable production experience with TypeScript across both frontend and backend (or significant TypeScript backend depth) - not just exposure as a frontend layer on top of a Python service. Python experience is required as a secondary language and can be at a working/contributing level rather than primary depth.
- 3+ years of experience building production software, including experience delivering full-stack applications and/or AI-enabled systems in production environments.
- Experience contributing to user-facing AI product features, from backend services through frontend implementation.
- Experience working with agentic systems in production or pre-production, including tool calling, multi-step workflows, RAG, or structured output handling.
- Exposure to evaluation frameworks, including golden datasets, regression gates, or CI controls for quality assurance.
- Experience working with containerized environments such as Docker and Kubernetes, including familiarity with monitoring and reliability practices.
Full-Stack Product Engineering
- Experience building modern full-stack applications with frontend architecture and backend integration.
- Strong TypeScript proficiency as the primary language for full-stack work: Component-based UI development, strict TypeScript (strict mode, generics, discriminated unions), API integration, and application state management. Comfortable owning non-trivial frontend architecture decisions, not just consuming patterns set by others.
- Production experience building TypeScript/Node.js backend services (Express, Bun, Koa, Fastify, NestJS, or equivalent) with end-to-end type-safe API contracts (tRPC, Zod, OpenAPI codegen, or similar). Comfortable owning the boundary between TypeScript frontends and TypeScript and/or Python backends.
- Strong relational data modeling skills: comfortable writing and reviewing raw SQL, designing normalized schemas, and reasoning about tables, views, indexes, and foreign-key relationships rather than relying solely on ORM-generated patterns.
- Practical PostgreSQL depth: query plan analysis, JSONB usage patterns, and comfortable authoring and maintaining triggers and stored procedures where they’re the right tool.
- Comfortable owning schema evolution end-to-end: write safe, backwards-compatible migrations and reasons about migration safety in a multi-service production environment.
- Familiarity with the modern TypeScript tooling stack: yarn, pnpm, or npm workspaces, ESLint, Prettier, Vitest or Jest, and build tooling (Vite, Turbopack, esbuild). Treats type-safety, linting, and testing as production requirements, not optional polish.
- Experience building product experiences for workflows such as tables, document-centric interfaces, review flows, or real-time/streaming interactions.
- Understanding of UX patterns for AI systems, including confidence indicators, citations/source grounding, fallback states, edit/retry patterns, and human review steps.
- Good product sense in translating non-deterministic AI behavior into usable and trustworthy product experiences.
AI Platform Engineering
- Working Python proficiency as a strong co-requirement (secondary to TypeScript), including FastAPI, Pydantic v2, async patterns, and pytest. Expectation: comfortable contributing to and reviewing Python services and LangGraph/agent service work.
- Hands-on experience with LangChain and/or LangGraph, including stateful graph construction, tool integration, checkpointing, and streaming patterns.
- Familiarity with Google ADK or equivalent agentic orchestration frameworks is a plus.
- Exposure to Temporal or similar durable execution frameworks, including workflow/activity authoring and retry patterns.
- Prompt engineering skills, including structured output design, system prompt construction, instruction clarity, and multi-turn context management.
- Experience implementing or contributing to RAG pipelines, including chunking, embedding selection, vector store integration, and retrieval quality evaluation.
- Familiarity with LLM evaluation approaches, including golden dataset design, metric definition, and regression gate concepts.
- Awareness of context window management strategies such as token budgeting, truncation, and tool-call state persistence.
- Familiarity with vector databases such as pgvector and/or OpenSearch.
- Experience with Docker and familiarity with Kubernetes deployment concepts.
Generative AI and Agentic Systems
- Uses AI coding assistants such as Cursor and GitHub Copilot as part of the development workflow, while applying judgement about where generated code is reliable versus where it requires scrutiny.
- Familiarity with multi-agent system concepts including orchestration logic, tool interfaces, and failure-handling patterns.
- Capable of contributing to evaluation pipelines that combine deterministic metrics with LLM-as-judge patterns for qualitative assessment.
- Able to review AI-generated code, including Kubernetes manifests, prompts, and agent graphs, for correctness and safety before production release.
General
- Understands non-determinism as a first-class engineering challenge and contributes to systems that degrade gracefully when model outputs are unexpected.
- Writes evaluation tests before shipping new AI capabilities, not after.
- Prototypes quickly using AI tooling, but validates production artifacts against defined quality gates before promotion.
- Documents behavior specifications, tool contracts, and user-facing interaction patterns rather than leaving critical behavior implicit in code.
- This role follows a hybrid model, requiring in-office presence at least 1 day per week
