Description 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 Requirements What is needed to succeed? 5+ years of professional software engineering experience Strong, hands-on background in Go in production systems Working proficiency in React — able to build and maintain UI components/pages, even though the role is primarily backend Strong quality awareness — you think about testability and edge cases as you design, and you're comfortable jumping into test automation alongside QA when needed Comfortable contributing to test automation, ideally backend automation in Go and/or front-end automation in Cypress (or a similar framework, with willingness to pick up Cypress) Practical experience using AI coding assistants (e.g., GitHub Copilot, Claude Code, Cursor) as part of your regular development workflow, and comfortable adopting them as standard practice on this team Excellent understanding of modern distributed software architecture: microservices, gRPC/REST APIs, message queues, relational databases (PostgreSQL) Experience with Docker and Kubernetes Experience developing with modern Agile methodologies (Scrum, CI/CD, TDD) Quick to learn new technologies and apply them to complex problems Highly organized, with strong quality and delivery discipline; self-managed and flexible to change Excellent English communication skills (verbal and written) Strong team player Nice to have Experience with Cypress specifically for end-to-end front-end testing Application/cyber security background Experience with GitOps and Infrastructure-as-Code tooling (Terraform, Helm, ArgoCD) Experience with OpenTelemetry or production observability tooling What we have to offer Checkmarx offers a great work environment, professional development, challenging careers, competitive compensation, great work-life balance, as well as great benefits and perks throughout the year.
