Senior Software Engineer (Go)

Who are we?​ Checkmarx is the AI-powered application security leader helping the world’s most security- conscious enterprises secure the software that powers modern life. For more than two decades, our unified platform and services have helped organizations protect human- and AI- generated code from the first line through runtime, reducing risk across applications, cloud, and the software supply chain without slowing innovation.​ ​ We’re trusted by 1,600+ customers in 70+ countries, including some of the largest enterprises and governments in the world. Guided by research-led innovation and a developer-first mindset, we help every developer, security team, and enterprise build software that is risk-free by design.​ What are we looking for? Chiron is a Checkmarx Core Platform R&D team that owns several core domains across our platform — including project and application management and risk management — that help customers understand and act on their security posture. We're looking for a Senior Backend Engineer to join the team as a core contributor, owning significant parts of the backend behind these capabilities. The role is backend-first and Go-centric, but you'll also touch the React front end when a feature calls for it — so comfort moving across the stack matters. Quality is a shared responsibility here: our QA partner owns most test automation, but team members regularly pitch in to keep automation coverage moving and avoid bottlenecks. ​How will you make an impact? Design and develop functional and technical capabilities within Chiron's large-scale, distributed backend systems, making ongoing architecture and design decisions Take full ownership of features and product areas end-to-end: architecture, coding, testing, CI/CD, and production observability Build and operate distributed microservices — gRPC/REST APIs, message queues, PostgreSQL-backed services — deployed on Kubernetes Build and maintain React components/pages (e.g., risk tables, single-risk views) that consume your backend services when a feature requires front-end changes Partner with our QA team on test automation — pitching in on backend automation in Go and front-end automation in Cypress when needed — to help keep coverage moving and reduce bottlenecks Use AI-assisted coding tools as part of your day-to-day development workflow, from writing and reviewing code to test generation and debugging Work smoothly with local and remote, multi-geo R&D and non-R&D teams, maintaining high visibility and effective communication Provide in-depth technical knowledge, guidance, and mentorship to other team members as needed Participate actively in design discussions and code reviews, holding the team to high execution and quality standards
