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.

• Strong programming skills in one or more languages (Python, Go, Java, etc.)

• Strong diagnostic and debugging skills, with a proven ability to root-cause complex production issues

• Curiosity and persistence — a drive to understand problems fully and see them through to resolution

• A customer-obsessed mindset: you take pride in delivering accurate, high-quality solutions that delight customers

• Excellent communication skills, with the ability to work effectively with customers and cross-functional teams

• Solid understanding of distributed systems, microservices, APIs, system design, and cloud infrastructure (AWS preferred)

• Experience working with data pipelines, ETL systems, or high-volume data processing
