## About the Role

Simplicity & Creativity: Favors the simplest design that solves the problem; brings creative thinking to product and technical problems and can explain the tradeoffs behind a choice

TypeScript: Strong experience across frontend and backend systems

Frontend: Vue 3 / Nuxt experience, ideally with large production applications

Backend & APIs: Node.js backend/API development; experience designing and maintaining REST APIs and OpenAPI contracts; AdonisJS familiarity is a plus

Search & Geospatial: Experience with search-heavy applications, geospatial data, or Elasticsearch/OpenSearch is a plus

Engineering Discipline: Strong testing and code-review discipline; able to work within an established architecture rather than introducing unnecessary complexity

Ownership: Comfortable owning work end-to-end, including scoping, implementation, rollout, and production support

Building with LLMs: Hands-on experience building with LLMs, tool use, agents, structured outputs, retrieval, and multi-step workflows

Agent Systems: Familiar with agent orchestration, tool calling, memory/context strategies, evals, guardrails, and failure handling

AI Judgment: Keeps a strong pulse on emerging AI models, agentic patterns, and tooling; evaluates new model classes and frameworks on real tradeoffs in quality, latency, cost, reliability, and maintainability; regularly experiments and can separate useful advances from hype

## Description

You will join the Seerist software engineering team to build and evolve the core of our intelligence platform: the TypeScript applications, APIs, and search experiences that analysts and customers rely on every day, and the AI-driven features that are changing how they work. We are looking for a creative engineer who values simplicity. You look for the plain solution to a hard problem, you leave the codebase easier to understand than you found it, and you work within an established architecture instead of adding complexity for its own sake. You will own work end to end, from scoping and implementation through rollout and production support. You will also help us tell the AI advances that matter from the hype, because you build with them.
