DigiCert Quantum Central is the platform helping enterprises get ahead of that transition: discovering cryptographic assets, identifying vulnerabilities, prioritizing remediation, and managing their migration to post-quantum cryptography (PQC). The Quantum Central engineering team is looking for a full stack Senior Software Engineer to help build this platform from the ground up. This is greenfield, high-impact work on a problem the industry hasn't fully solved yet. You'll design APIs, own features end-to-end, and ship software that some of the world's largest organizations depend on to stay secure. We move fast. We use AI as a force multiplier. And we hold the bar high on quality — because in security, cutting corners isn't an option. What you will do Build RESTful, highly scalable cloud-native services in Go and TypeScript Own features end-to-end: design, implementation, testing, deployment, and observability Use AI coding agents (Cursor, GitHub Copilot, Claude Code, etc.) as a native part of your daily workflow — fluently, not occasionally Design and ship software using agentic AI workflows: LLM orchestration, autonomous pipelines, and AI-assisted product features where relevant to the Quantum Central platform Collaborate with engineers, product managers, and security researchers to build PQC readiness tooling the market doesn't yet have Engage with engineering leaders to implement industry best practices and drive technical decisions Analyse, troubleshoot, and debug product defects and deliver timely solutions Develop a deep understanding of post-quantum cryptography, PKI, and the cryptographic asset landscape What you will have +5 years of professional software engineering experience Expert proficiency in Go for designing and building RESTful, cloud-native web services Strong TypeScript backend development skills Fluency with AI coding agents (Cursor, GitHub Copilot, Claude Code, or similar) as a daily, production workflow — you use them to ship faster and with higher quality, and you bring the judgment to review what they produce Hands-on experience building with agentic AI workflows : LLM API integration, function-calling pipelines, autonomous agents, or AI-assisted development pipelines in production or near-production systems Strong knowledge of software engineering best practices: design, testing, architecture, and code quality Experience with service-based architectures and distributed systems Solid understanding of relational databases, SQL best practices, indexes, and query optimization Familiarity with Test Automation Frameworks and CI/CD pipelines Exposure to AWS or equivalent cloud infrastructure Ability to identify where AI can accelerate delivery and advocate for AI-first engineering practices within the team Strong communication and collaboration skills Nice to have Understanding of post-quantum cryptography (PQC) , SSL/TLS, PKI, or cryptographic asset management Familiarity with NIST PQC standards (Kyber, Dilithium, etc.) Experience with cryptographic discovery tools, CMDB integrations, or security posture management platforms Bachelor's degree in Computer Science, Information Systems, or equivalent industry experience Experience building multi-agent AI systems or RAG-based features integrated into real product workflows Technologies and tools we use — any experience is a bonus: Go MySQL / MariaDB
