Job description

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.

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 What We Offer We believe people do their best work when they feel supported, trusted, and valued. VulnCheck offers benefits designed to meet a wide range of needs and lifestyles: Benefits and Perks Unlimited PTO 401k plan with 100% match on first 3%, then 50% of the next 3-5% of compensation Comprehensive healthcare coverage Generous paid parental leave Remote friendly environment with flexibility Expense reimbursement for Cell Phone & Internet Ongoing professional development, coaching, and learning resources Opportunities for career advancement within a fast-growing team Why Join Us Built on over two decades of cybersecurity experience, our team of experts understands the intricacies of vulnerabilities, their exploitation in the wild, and how to leverage this data to build more effective cybersecurity products that produce better outcomes for organizations.
