About Plexi

Plexi is two connected products. Plexi Fact is our data lakehouse platform - we pull data from dozens of vendors, clean it, model it, and serve it back through dashboards, APIs, Excel, and AI agents. Enterprise clients, real traction, growing fast. Plexi Flexor is the agent platform we use to build everything else - 50+ specialized agents that pair with us on architecture, testing, code review, data modeling, security, and more. We don't just use those agents. We design them, refine them, and ship the patterns we find.

Why You Want to Be Part of This Story

If you've been pushing what Claude Code or Cursor can do beyond autocomplete - if you have opinions about prompts, agent design, and where this is all going - you'll be at home here. You'll work directly with the founders. You'll have a roster of agents reviewing your PRs, suggesting refactors, writing tests, and generating docs, and you'll be writing the skills and prompts that make them better. The work moves fast and the bar is high; you'll learn quickly.

You'll be trusted to find what needs doing, dive in, build the context, make a plan, and ship - pulling others in when their expertise is genuinely needed. We're a small team and there's more work than people. That's the deal, and it's also the opportunity.

What You'll Actually Do

• Ship full-stack features end-to-end: SvelteKit UI, Flask/Python API, SQL Server back end - often all three in the same week
• Pair with AI agents the way you'd pair with a senior engineer: direct them, review their work, push back when they're wrong
• Write Flexor skills and hooks that make our platform better for everyone on the team
• Build and maintain REST endpoints (100+ today, growing)
• Write SQL against a mature data model and learn what a real production database actually looks like
• Sit in on client calls, watch how the platform gets used, and ship the thing they asked for that same week
• Contribute to architecture and product decisions - we don't gatekeep that to senior people

Tech Stack

What Matters

• You're a self-starter who drives a problem end-to-end - dive in, build understanding, make a plan, execute, and pull others in when their expertise is needed. You don't wait to be told what to do, and you don't get stuck waiting for permission.
• You actually code - degree, bootcamp, previous job, or side projects that wouldn't quit. We care what you can do, not how you got there.
• You already use AI in your dev workflow and you push it harder than your friends do
• You can hold both ends of the stack in your head - a typed front-end framework (Svelte/React/Vue) plus Python or another backend language
• Basic SQL fluency or hunger to get there fast - real SQL, not just SELECT *
• You ask good questions before you code
• You read existing code carefully before adding new code
• You're comfortable being uncomfortable: new stack, new client, new pattern

Nice to Have (We'll Teach You the Rest)

• A side project, GitHub repo, demo, or anything you've shipped that you're proud of
• An MCP server, Claude skill, custom agent, or hook you've built or extended
• SvelteKit or Svelte 5
• T-SQL or PostgreSQL beyond basics
• Azure cloud experience
• Curiosity about financial data, fintech, or asset management
