About The Position

Further is a data, cloud, and AI company focused on helping businesses make the right decisions from raw data. We have an award-winning culture and aim to enable people to thrive so that businesses can thrive. We believe in meaningful work that has a positive impact. This role is for a full-stack engineer who can handle complex problems from data layer to UI and model gateway. LLM integration is a core part of the daily work. The role involves writing NestJS services, consuming events, exposing data through APIs, building a console UI, and integrating LLMs as governed components with prompt versioning, evals, observability, and cost discipline. The codebase is strict TypeScript, opinionated, and well-documented, requiring adherence to high standards from day one. The position is based at our headquarters in Dallas, TX, with a hybrid schedule, requiring in-office presence on Tuesdays, Wednesdays, and Thursdays.

Requirements

7+ years of production TypeScript and Node.js experience, with a strong reflex for writing strict TypeScript.
Production experience with NestJS or a comparable Node.js framework, demonstrating understanding of the request lifecycle, dependency injection, and trade-offs.
Production experience with Next.js (App Router preferred) and modern React, including server components, streaming, and client/server boundary discipline.
Shipped LLM-powered features to production, with experience in prompt drift, eval design, hallucination handling, and cost management.
Working-level experience with PostgreSQL, including migrations, index design, query plan analysis, and trade-off reasoning.
Experience with event-driven architecture, including pub/sub, idempotent consumers, eventual consistency, ordering, retries, and dead-letter behavior.
Strong testing instincts for unit, integration, and end-to-end tests, with a focus on tests that matter.

Nice To Haves

Drizzle ORM, Temporal, or Redpanda/Kafka in production.
OpenTelemetry beyond surface-level, including sampling strategy, semantic conventions, and custom instrumentation.
Design system contribution, including component libraries, accessibility patterns, and design token discipline.
Experience with agent frameworks (LangGraph, custom orchestration), eval tooling (Braintrust, LangSmith), or prompt versioning systems.
Open-source contributions to the TS/Node/Next ecosystem.

Responsibilities

Develop backend services in NestJS, including API design, request validation with Zod, event publishing through the canonical SDK, projection consumers, and RLS-aware database access.
Build the Next.js console using the App Router, server and client components, the in-house design system, real-time UI patterns, and the widget framework to make complex platform state intuitive for operators.
Integrate LLMs, including agent orchestration within the workflow runtime, prompt engineering with version control, evaluation harnesses, model gateway usage, structured output validation, and retry/fallback logic, treating model calls as production code.
Implement observability features, including OpenTelemetry traces, structured logs, and meaningful metrics to ensure issues are easily discoverable.
Contribute to the engineering culture by setting a high bar for new engineers and mentoring them through their PRs.
