About the role

aikidosecurity's standard text

🌍 We’re making security suck less for developers.

Security tools haven’t kept up with how software is built today. They interrupt teams, slow releases, and turn security into a bottleneck instead of a capability. We built Aikido to change that. Aikido builds developer-first security products that reduce real risk without getting in the way of shipping software. We focus on what actually matters and automate the rest.

We’re taking on legacy security tools teams have been stuck with, and we’re winning. If you want to help us take market share and build products developers actually enjoy using, you’re in the right place.

Founded in 2022 by third-time founders, Aikido has $85M in the bank and a long runway ahead. We’re building toward self-securing software. Join an all-star team. Take real ownership. Push boundaries. Build things that matter.

As a full-stack developer, you’ll be working closely with the Noon team at Aikido. Noon is our new workforce security product, protecting people from AI-powered attacks such as phishing, malware and deepfakes. It brings together email protection, device protection, AI governance, and attack simulations and training in one platform. You’ll help build the core of it from an early stage.

Responsibilities

  • Write modular, testable, and efficient code using TypeScript, Node.js (Fastify) and React.
  • Build and maintain APIs and data models on PostgreSQL.
  • Design and implement high-availability applications.
  • Discover, plan, write, document and maintain new features.
  • Understand the fundamental design principles behind a scalable application.
  • Understand the nature of asynchronous programming and its quirks and workarounds.
  • Optimize the product code for speed where required.
  • Really comfortable in a very entrepreneurial environment
  • Strong problem-solver who learns fast and adapts
  • Can think along with architectural and impactful decisions
  • Willing to learn new languages when the product requires it (Rust or Go is a bonus)
  • Comfortable researching and tackling hard problems and algorithms (e.g. parsing)
  • Willing to experiment (and also willing to perhaps throw away some code)
  • Medior to Senior:
  • We are going fast and need experienced people that can hit the ground running with us.
  • You need to be comfortable with Node.js, TypeScript and React. SQL experience is enough, deep PostgreSQL expertise is not needed.
  • No stranger to implementing automated testing platforms and unit tests
  • Bonus: technical knowledge of email, EDR or malware
  • Fluent in English
  • Candidates must be able to work from our offices in Ghent, Warsaw or Chicago.

What you can expect

  • Short decision lines. Big ownership. Shape the projects that matter and ship fast.
  • Grow as fast as we do. Take on more, own more, and carve out your own path.
  • Top-tier tech pay and equity.
  • High trust, strong values, zero corporate BS.
  • Flexibility in working hours.
  • A company that sticks to its values in an open and informal atmosphere.
