Join our mission to secure the universe of code.

Our story

Aaron and Louis were working together on a government contract for an organization that used lots of open source software. They looked for a solution that could identify malware lurking in open source dependencies. They found inadequate legacy products that merely focused on vulnerabilities. To address this major gap, they teamed up with Pete to build Phylum and define the future of software supply chain security.

About Us

At Phylum, we defend the world’s vulnerable software from malicious actors. We’re on a mission to build the next generation of DevSecOps tools, beginning with our flagship effort to defend the software supply chain from cyberattack. We’re a cybersecurity product company that protects all kinds of software, from open-source software to proprietary enterprise and embedded devices to web applications. Everything about our company is developer-first. We’re founded by software developers, and our primary user is the software developer. As a venture-backed startup, we’re off to the races. Now is an exciting time to join our team and have a huge impact!

About You

Since our primary users are other developers, we focus heavily on product extensibility. As a developer yourself, you’ll create products for a community that you know inside and out. You’ll set project direction and have a meaningful contribution on Phylum’s big technical ideas.

Your role will accelerate our progress via improved:

  • Prioritization: reach decisions and drive focus
  • Accountability: record what’s decided and follow up
  • Effectiveness: promote best practices, define processes as well as search out and resolve areas of operational friction

Requirements

  • Experience with full stack development, program analysis, machine learning or data science preferred
  • Breadth of experience preferably with Rust
  • Experience leading projects and collaborating with a team to create meaningful impact
  • Architected systems to solve a variety of product and data needs
  • Strong fundamentals in computer science, software engineering, and algorithms

The Tech Stack

Our engineering team embraces modern software engineering practices. All of our code runs in a continuous integration environment with good testing. We primarily deploy on Linux environments and lean heavily on Docker. Much of our code is written in Python, Rust, and Scala.

Phylum’s ingestion platform is built around Kafka. We store our datasets with Hadoop, leveraging Hive, HBase, and Elasticsearch, and we lean on Spark for analytics. All of our infrastructure sits on Kubernetes. Phylum’s front-end stack uses modern Javascript, React, Redux, ImmutableJS, d3.js, and all the usual front-end tooling like webpack and babel. We interact with projects that make extensive use of Scala, C, and C++.

Compensation

  • Competitive salary commensurate with experience ($140,000 - $150,000)
  • Meaningful stock options
  • Exceptional medical, dental, and vision (with premiums paid 100% by Phylum)
  • 401k with 3% company contribution whether you participate or not
  • Unlimited paid time off
