Description
OX Security is securing the AI-driven SDLC from prompt to production. We're building the next generation of security technology for a world where AI is changing how software is built, deployed, and attacked.
We're growing fast and looking for a Senior Backend Engineer to join our AppSec Solution group, home of OX's core platform, and play a key role in shaping the architecture and infrastructure the whole product runs on.
This is a high-impact, cross-functional role where you'll work closely with our Software Architect, team leads across R&D, DevOps and Product, helping us build the foundations for what comes next, including running AI agents inside the product at scale.
If you're independent, opinionated and love turning a design on a whiteboard into a production system, we'd love to meet you.
Responsibilities
What You'll Be Doing

Own cross-company infrastructure and architecture projects end-to-end with our Software Architect, from design through adoption across teams

Build and own the shared foundations and standards our services are built on

Lead the evolution of our data layer as our largest customers scale

Build the platform foundations for running AI agents inside the OX product

Drive cost optimization from the application side, including how our services scale on Kubernetes

Raise the reliability and observability bar across our services

Lead how R&D builds with AI, so AI-assisted development is fast and meets our engineering standards

Lead technical alignment with team leads, DevOps, and Product: bring a clear point of view and move cross-team initiatives forward

Act as an internal partner for engineering teams: review designs, find reuse, and raise the architectural bar across R&D

Stay hands-on: write platform code and land changes across teams

Requirements
What We're Looking For

7+ years of backend engineering experience, with architect-level depth in system design

Strong production experience with Node.js and TypeScript

AI-first: you build with AI tools every day, adopt new AI technologies early, and look for ways AI can improve developer experience and system performance

Deep experience with databases at scale: data modelling, performance, and evolving a data layer in production

Proven hands-on experience in platform engineering and infrastructure, including shared foundations adopted across teams

Hands-on experience with Kubernetes and a strong understanding of DevOps practices

Track record of leading cross-team technical projects and influencing without formal authority

Clear written communication: design docs and technical reviews

Nice to have

Practical understanding of LLMs and AI agents

Experience with cloud cost optimization

Background in cybersecurity or SaaS

The "AI-First" Spark: You are an early adopter of AI technologies and are passionate about finding ways to use AI to improve developer experience and system performance.
