The posting

Sr. Software Engineer - US

Location: Massachusetts, Maryland, or Greater Austin, TX (Remote) Team: Product & Engineering Employment Type: Full-Time

About VulnCheck

Exploitation prevention is only as strong as the intelligence driving those efforts, and most of the industry is still running on intelligence that lacks exploit context. VulnCheck, The Exploit Intelligence Company, delivers structured exploit intelligence on what is actively weaponized in the wild, purpose-built for the data lakes, ETL pipelines, automation, and AI and LLM workflows your infrastructure already runs on, raising the capability of everything it powers.

About the Role

We’re looking for a Senior Software Engineer to design, build, and scale the core systems that power VulnCheck’s vulnerability intelligence platform. This is a high-impact, hands-on role where you’ll own critical services and data pipelines end-to-end—from design through production.

You’ll play a key role in shaping architecture, improving system performance and reliability, and delivering features that directly impact customers. While you’ll help resolve production issues, your focus will be on building durable, scalable solutions that prevent them. Although this is a 100% remote role, preference is for candidates located in either Greater Boston, DMV (Delaware, Maryland, Virginia), or Greater Austin, TX.

What You’ll Do

  • Design and build scalable backend systems, APIs, and data pipelines
  • Own services end-to-end, including architecture, development, deployment, and operation
  • Lead technical design discussions and contribute to system architecture decisions
  • Write high-quality, maintainable code and drive engineering best practices
  • Debug complex production issues and implement long-term, scalable solutions
  • Improve system performance, reliability, and observability across the platform
  • Partner closely with Product, Data, and other Engineering teams to deliver impactful features
  • Mentor junior engineers and contribute to a strong engineering culture
  • Participate in incident response and on-call rotations

What You’ll Bring

  • 5+ years of experience building and scaling backend systems as a software engineer
  • Strong programming skills in one or more languages (Python, Go, Java, etc.)
  • Experience in cybersecurity, vulnerability management, or threat intelligence
  • Experience designing distributed systems and working with microservices architectures
  • Deep understanding of APIs, system design, and cloud infrastructure (AWS preferred)
  • Experience working with data pipelines, ETL systems, or high-volume data processing
  • Proven ability to debug and optimize production systems
  • Strong ownership mindset with the ability to lead projects independently
  • Excellent communication skills and ability to collaborate cross-functionally

Preferred Qualifications

  • Familiarity with CVE, NVD, KEV, or exploit intelligence datasets
  • Experience with streaming systems or real-time data processing
  • Background in high-growth or startup environments

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
