Who we are
CryptoNext Security builds the cryptography that protects the world's data once quantum computers can break today's encryption. Founded in 2019 out of 20+ years of research at INRIA, CNRS and Sorbonne, we are recognised by Gartner among the global top 5 PQC vendors and are the first European company selected by NIST's NCCoE on post-quantum migration.
Our R&D team has built the technology that brought us to market. We now need an Engineering Manager to take ownership of how this team works: increase its productivity, set a clear architecture vision, and balance the short-term pressure of shipping features against the long-term need to pay down technical debt.
This is a builder's role. You will report to the CTO (and work closely with Product to ship a roadmap that customers (banks, governments, infrastructure operators) are already buying.
What you'll do
• Lead the R&D team day-to-day. Run 1:1s, set objectives, recruit, and develop people.
• Own the architecture vision. Make our products scalable as we move from early customers to large-scale deployments. Define the patterns we use, the boundaries between services, and how we evolve our current products) without breaking customer integrations.
• Run the tech-debt-vs-features trade-off. Work with the CTO and Product to decide what we refactor, what we ship, and in what order. Make this explicit, visible and defended to the rest of the company.
• Increase team productivity. Diagnose what slows us down, fix it. CI/CD, observability, code review culture, sprint rituals, ownership boundaries - whatever the bottleneck is, you own it.
• Define and monitor Engineering KPIs and dashboards to track delivery performance, velocity, development efficiency, quality metrics, and team capacity utilization.
• Analyze engineering data to identify bottlenecks, improve predictability and operational efficiency, and support data-driven decision-making
• Partner with Product and Customer-facing teams. Translate customer needs into deliverable engineering work. Shield the team from chaos, but also bring them close enough to customers that they build the right thing.
• Report up to the CTO and exec team. Clear, honest visibility on progress, risks, and resource needs.
