Full-Stack Software Engineer (Frontend-Focused) – AI Infrastructure / Open Source

We are building the next generation of open-source developer tools that power AI integrations at scale. Our platform enables organizations to securely connect AI agents, LLM-powered tools, and enterprise systems using modern protocols and open-source infrastructure. As we help define how developers build with AI, we’re looking for engineers who care about clean design, exceptional user experiences, and open-source collaboration.

About the Role

We’re searching for a Full-Stack Software Engineer with a strong front-end focus to build elegant, performant interfaces for developers interacting with AI tooling, system integrations, and cloud-native infrastructure. If you’re passionate about frontend craftsmanship—but comfortable working across the full stack—this role offers the opportunity to influence a fast-growing open-source ecosystem.

Experience with AI, LLM agents, or Model Context Protocol (MCP) is a plus, but not required. Curiosity and strong engineering fundamentals matter most.

Key Responsibilities

  • Design and implement polished front-end interfaces using Svelte and/or React, with a strong emphasis on usability, developer experience, and performance.
  • Build full-stack features across modern open-source tooling (Node.js, Python, Go, TypeScript—any strong backend experience in OSS languages is welcome).
  • Develop and maintain interfaces for discovering, managing, and interacting with AI/LLM tools, integrations, and system connections.
  • Work closely with product and platform engineering teams to turn complex workflows into intuitive, accessible UI flows.
  • Own features from design, architecture, development, testing, documentation, deployment.
  • Contribute actively to open-source discussions, pull requests, documentation, and best practices.
  • Help shape and refine the developer experience for a new category of AI and integration tooling.

Ideal Candidate

Experience

  • 8+ years of professional software development experience, with a substantial emphasis on front-end engineering.
  • Deep experience with Svelte (preferred) or React, plus strong TypeScript fundamentals.
  • Full-stack proficiency with one or more open-source backend languages (Node.js, Python, Go, etc.).
  • Experience building developer tools, dev-platform systems, cloud-native tools, or open-source infrastructure is highly valuable.
  • Exposure to AI tooling, agents, or MCP is a plus—but not required.

Open-Source Mindset

  • A strong record of open-source contributions (PRs, issues, personal projects, community involvement).
  • Comfortable working in public repositories and collaborating in the open.
  • Background in open-source-focused companies or developer-tool startups is a bonus.

Soft Skills & Attributes

  • Excellent communication skills and a collaborative, low-ego approach to engineering.
  • Ownership-driven: you take pride in building clean, maintainable software end-to-end.
  • Logical, consistent career progression — not looking for contractors or frequent job-hoppers.
  • Strong curiosity about emerging technologies, developer experience, AI systems, and open-source ecosystems.

What We Value

  • Humble collaborators: You elevate your teammates and help build a strong engineering culture.
  • Craftsmanship: You care about design quality, reliability, and long-term maintainability.
  • Curiosity & Drive: You love solving difficult problems and exploring new technologies.
  • Community Orientation: You enjoy contributing to open-source and building tools developers want to use.

Why Join Us?

This is an opportunity to:

  • Build open-source software used by developers worldwide.
  • Work on the emerging ecosystem powering AI/LLM integrations and developer tooling.
  • Create high-impact features in a small, senior, highly technical team.
  • Influence the direction of a rapidly evolving space with enormous upside.
  • Work on meaningful problems at the intersection of frontend engineering, AI systems, and open-source innovation.

If you're a front-end expert who enjoys working full-stack, loves open-source, and wants to help shape the next wave of AI-driven development tools, we’d love to talk with you.
