Senior Software Engineer
Posted 2026-06-26We are looking for a talented Senior Software Engineer to join our team!
PolySwarm is developing innovative solutions to age-old information security problems - and we need your help. The PolySwarm marketplace is a launchpad for new technologies and novel threat detection methods, where commercial solutions and independent researchers compete to detect threats, and get compensated based on performance.
At PolySwarm, you'll join a tight, dynamic team on the bleeding edge of information security. On a typical day you will be implementing features or building new microservices in Django or Flask+SQLAlchemy, integrating that with a NodeJS frontend or other internal Python or Rust based microservices. You will test your work in a local end-to-end testing environment. When you are ready, you’ll push your work to GitHub for code-review and testing in GitLab CI. When your work passes CI and code review, you’ll be able to test your work in our staging environment, you’ll need to write or revise Kubernetes charts and values, so your code will deploy correctly to our cluster. When all is good, you’ll coordinate with the team to deploy it to production at the next production release.
Other days you may be helping a security expert create their microengine and get it deployed in the marketplace. Or maybe you’ll be building or improving the PolySwarm integration for a threat intelligence product.
When it is time to build new services or major features, you may be the main architect, and even if you are not, we will definitely ask for your input into the design and implementation details. We are a small team and share a diverse set of tasks across the team, so you’ll be able to have an impact anywhere you show interest.
With your expertise and experience, you will play a critical role in making PolySwarm the most competitive anti-malware platform available. Senior hires will be entrusted with broad decision-making responsibility concerning architecture, infrastructure, deployment, scale, access control, continuous integration, tooling, and much, much more.
If you are an ambitious, seasoned developer interested in creating solutions to the most challenging and pressing security challenges of the moment, we are interested in speaking with you.
What we offer:
Competitive salaries
Excellent health, dental, vision coverage (US employees)
401k (US employees)
Paid time off (US employees)
Flexible work hours. We have core work hours for overlap between time zones, but outside of that block of hours, you can schedule your working hours as you like to get things done.
Powerful laptops and desktops - whatever you need to be most productive!
