Why join AquilaX?

Security engineers building for security engineers

🎯

Mission That Matters

Every line of code we ship makes real software more secure. We're not building yet another CRM β€” we're protecting the software that runs banks, hospitals, and governments.

🏠

Remote-First Culture

Work from anywhere. We're a distributed team and we've built our culture around async-first communication and deep work. No performative office hours.

🧠

Cutting-Edge AI Work

We're building self-learning security AI that nobody else has built. If you want to work at the intersection of AI and application security, this is it.

πŸ“ˆ

Equity & Growth

We offer meaningful equity. As an early-stage company, the people who join now are the ones who build the foundation β€” and share in what we create together.

πŸ“š

Learning Budget

Security moves fast. We invest in your learning β€” conferences (DEF CON, Black Hat, BSides), courses, certifications, and anything that makes you better at your craft.

πŸ”¨

Builder Culture

No committee approvals for every line of code. No six-month roadmap reviews. We ship, we learn, we iterate. You'll have real ownership over what you build.

You'll design and build the core scanning capabilities of AquilaX's platform β€” writing the detection logic, tuning the analysis engines, and helping define how Securitron AI makes security decisions. This is where AppSec depth meets engineering excellence.

What you'll do

  • Build and maintain SAST, SCA, and secrets scanning engines
  • Research new vulnerability classes and implement detections
  • Define false positive reduction strategies with the AI team
  • Write threat models for scanner edge cases
  • Contribute to our public security research blog

What we're looking for

  • 5+ years in security engineering or AppSec
  • Strong Python and/or Go skills
  • Deep understanding of OWASP Top 10, CWE taxonomy
  • Experience with AST analysis, code parsing, or static analysis
  • Threat modeling and vulnerability research experience
  • OSCP, CEH, or similar (nice to have)

AI / ML Mid–Senior Remote / UK
Apply β†’

You'll work on Securitron AI β€” the self-learning engine at the heart of AquilaX. This means building RAG pipelines for security knowledge, fine-tuning LLMs for vulnerability detection, and creating the per-organization learning systems that make AquilaX's false positive rate near-zero.

What you'll do

  • Build and improve LLM-powered security analysis pipelines
  • Design per-organization self-learning models
  • Implement vector embeddings for code semantic search
  • Build AI-powered remediation suggestion systems

  • Python expertise (PyTorch, Hugging Face, LangChain)
  • Security domain knowledge (AppSec, vulnerability research)
  • Experience fine-tuning or evaluating LLMs for specific domains
Frontend Engineer
Engineering Mid–Senior Remote / UK
Apply β†’

Security tools fail when developers don't use them. You'll build the interfaces that make AquilaX's findings accessible, actionable, and integrated into developer workflows. Our UI should make security as natural as writing code.

What you'll do

  • Build the AquilaX web application and dashboards
  • Create developer-friendly finding views with remediation flows
  • Implement real-time scan progress and terminal interfaces
  • Build VS Code and JetBrains IDE plugin features
  • Performance optimize complex security data visualizations

What we're looking for

  • 4+ years frontend engineering experience
  • React and TypeScript expertise
  • Experience building developer tools or security dashboards
  • Strong CSS and design instincts
  • Familiarity with WebSockets, terminal emulators (xterm.js) is a plus
DevSecOps Engineer
Engineering Senior Remote / UK
Apply β†’

You'll keep AquilaX's own infrastructure secure and help customers integrate AquilaX into their CI/CD pipelines. You're both the security practitioner keeping our platform hardened and the integration expert helping customers get maximum value from AquilaX.

  • Build and maintain CI/CD integrations (GitHub Actions, GitLab CI, Jenkins)
  • Implement security automation in our own SDLC
  • Help enterprise customers with on-premises deployments
  • Respond to and triage security incidents

What we're looking for

  • 4+ years DevSecOps or platform engineering experience
  • Kubernetes, Docker, Terraform expertise
  • CI/CD pipeline design and implementation
  • Security hardening of cloud infrastructure
  • Experience with on-premises software deployment
Security Researcher
Research Mid–Senior Remote / UK
Apply β†’

You'll stay ahead of the threat landscape β€” researching new attack patterns, developing proof-of-concepts for new vulnerability classes, and translating findings into detections that protect AquilaX customers before the community is aware of the threat.

What you'll do

  • Research emerging vulnerability classes and attack techniques
  • Develop PoC exploits to validate detection coverage
  • Publish security research (blog posts, CVEs, conference talks)
  • Translate research into AquilaX scanner improvements
  • Monitor CVE databases and threat intelligence feeds

What we're looking for

  • 3+ years security research or penetration testing
  • CVE disclosures or published security research (preferred)
  • Deep understanding of web, API, and supply chain attacks
  • Python and low-level programming skills
  • CTF experience or bug bounty track record is a plus
Sales Engineer / Solutions Architect
Sales Senior Remote / UK
Apply β†’

You'll be the technical face of AquilaX for enterprise customers β€” running demos, answering deep security questions, designing deployment architectures, and ensuring customers get maximum value from their AquilaX investment.
