This role is with one of Dex's trusted partner companies.
We work closely with their teams to truly understand their culture, goals, and what they're looking for, so we can match you with the right opportunity and give you context about the role before you commit to a process.

Tell Dex your stack, seniority, and what you want to build.
We will manage your applications and surface other opportunities that are a fit.
The role
This company is building an Agentic Operating System for a critical enterprise function, where AI agents are the core product, not an afterthought.
They've secured significant funding from leading investors and are experiencing rapid growth, scaling their platform to serve a rapidly expanding enterprise customer base.
They are recognised as one of Europe's fastest-growing companies.
You’ll join a dedicated platform team, serving a rapidly growing engineering organisation of 45+ engineers.
This isn't a Dev Ops or SRE role; you'll write production Type Script in a monorepo, owning the shared foundations that enable daily deployments across nine product domains.
Your impact is direct: you'll evolve their AWS serverless architecture for 10x growth, multi-region high availability, and data residency, setting the pace for the entire engineering team.
This is a senior or staff-level seat, focused on deep technical ownership and internal developer experience.
- The work
- Evolve a critical AWS serverless architecture (Lambda, Dynamo DB, Aurora, Event Bridge) to support 10x growth, multi-region high availability, and data residency.
- Own and extend Git Hub Actions pipelines and Pulumi infrastructure-as-code, ensuring robust, scalable deployment for 45+ engineers.
- Design and implement Datadog dashboards, SLOs, and alerts that proactively identify issues before customers are impacted.
- Write production-grade Type Script within a shared monorepo, building the core tooling and services that empower product teams.
- Automate away toil, building internal tools and workflows that improve developer velocity and experience across the organisation.
What You Bring
- You’ve deliberately specialised in platform or developer experience at a cloud-native Saa S company (50–500 engineers), not a recent pivot from Dev Ops or SRE.
- You write production code in Type Script; a scripting-only background (Bash/YAML) isn't a fit for this team.
- Deep, first-hand experience with AWS serverless (Lambda, Dynamo DB, Aurora, Event Bridge, IAM, networking), understanding the trade-offs.
- You’ve refactored a real infrastructure-as-code codebase (Pulumi, CDK, Terraform, or SST) and built reusable CI/CD workflows, deploy gates, and preview environments.
- You’ve built observability systems (dashboards, SLOs, alerts) that are genuinely relied upon and correctly page humans.

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.
