Founding Engineer (AI Startup) (E438C4D)

Some engineers enjoy writing code. Others can't stop building.

If you've been programming since you were a teenager, spend your evenings experimenting with new technology, and get genuine satisfaction from shipping products, this role was written for you.

Referment is partnering with a venture‑backed AI startup looking for one exceptional engineer to help build the next generation of AI‑powered cybersecurity products.

You'll work directly with the founders and own features from customer problem through to production.

You'll enjoy this role if you...

• Love building more than talking about building
• Prefer shipping software over writing documentation
• Can move between backend, frontend and infrastructure without thinking twice
• Get excited by hard engineering challenges like building compilers, DSLs, or internal developer tools
• Use AI every day, but don't rely on it to think for you
• Enjoy solving messy customer problems instead of perfectly defined tickets

What You'll Be Building

Rather than owning a small corner of a huge codebase, you'll own products end-to-end

• You'll design complex backend architecture and systems.
• Ship React interfaces.
• Build internal developer tools and agentic consoles.
• Improve databases and handle systems programming.
• Debug production and deploy continuously.
• Help shape both the product and the engineering culture.

What We're Looking For

• Deep technical focus on hard engineering and complex backend architecture
• Strong Python backend fundamentals with high-level application of tools like FastAPI, Django, or Flask
• Senior-level technical sophistication and the ability to move beyond routine maintenance tasks
• Verifiable track record of technical contributions and honest project claims (e.g. active GitHub or OSS presence)
• React experience or willingness to work across the frontend
• Startup mentality with genuine product ownership
• Around 3-6 years' experience with a focus on engineering depth

Extra points for experience with:

• Founding or leadership roles (e.g. Co-Founder or CTO)
• Building internal developer tools, DSLs, or compilers
• Multi-language proficiency (e.g. Go, C, or Rust)
• Cybersecurity
• Workflow orchestration (Prefect, Airflow)
• High-growth SaaS

This probably isn't for you if...

• Your focus is primarily on product management or innovation titles rather than hands‑on engineering
• You consider routine infrastructure maintenance to be your core focus area
• You need detailed specs before starting work
• You only enjoy one part of the stack
• You avoid production responsibility
• You're looking for a comfortable corporate engineering role
• You're currently splitting your attention with another startup

Why join?

• Competitive salary
• Meaningful equity
• One of the first engineering hires
• Direct access to the founders
• Huge ownership from day one
• Build products that customers actually use
