The role
Security teams waste cycles re-investigating the same vulnerabilities.
This platform answers security questions once, provides the evidence, and keeps that answer true as environments shift.
It then hands the root cause to coding agents, stopping the same class of bug from shipping again.
The company is backed by leading VCs and already works with early customers.
You'll join a small, founding team, owning the entire path from data model to the UI that makes an answer readable, including the evaluation that proves it's right.
This isn't just building features; it's solving a moving target problem: answering complex security questions across estates too large for a single model, where facts constantly change.
You'll work directly with the founder and customers, shipping Python and Prefect on the backend, React on the frontend.
- The work
- Own the full stack, from data ingestion and modeling to user-facing interfaces and the evaluation proving correctness.
- Tackle complex, question-first problems: determine the evidence needed to settle a security flaw, then build the systems to gather it.
- Navigate vast, dynamic customer environments that defy simple modeling, ensuring answers remain accurate as conditions change.
- Deliver end-to-end solutions, like identifying and removing unwanted packages across an entire customer estate.
- Engage directly with customers to understand their problems and validate your solutions.
What You Bring
- Strong engineering fundamentals: databases, testing, and operating production systems. Python is core; React is a significant plus.
- Experience shipping LLM-powered products, with a clear understanding of how to measure and prove their improvement.
- The ability to build and ship effectively in a lean, early-stage environment, moving fluidly between backend, frontend, and problem-solving.
- A track record of owning customer problems from initial conversation through to production deployment.
- Enough experience to trust your judgment and adapt your approach, valuing variety over rigid methodologies.

How to prepare for a job interview at Dex
✨Brush Up on Your Coding Skills
For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.
✨Know Your Tools and Frameworks
Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If Dex uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.
✨Showcase Your Projects
Bring along a portfolio that highlights our best work. This could be code samples, GitHub repositories, or any side projects we’ve built. Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.
✨Prepare for Behavioural Questions
While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
