It includes both enterprise-grade and small form factor crypto devices, together with the key management and other related systems that support them. These products form the backbone of our secure mobility solutions, integrating into our gateways and into customer mission environments. They deliver world-leading security whilst being evaluated against the most rigorous government standards.\u0026nbsp;\u003cbr\u003e \u0026nbsp;\u003cbr\u003e At Senior Product Manager level, you would own that portfolio end to end - the product vision, roadmap, commercial position and assurance pathway.\u0026nbsp;\u003cbr\u003e At Principal Product Manager level, you would own that and the wider product family around it: arbitrating between products competing for the same engineering capacity, carrying commercial performance across the family. Line management of product managers would be expected to follow within the next 12-18 months.\u0026nbsp;\u003cbr\u003e \u0026nbsp;\u003cbr\u003e At either level you will navigate a set of genuinely interesting tensions: the convergence of hardware and software in our solutions; assurance constraints against user experience; agile delivery against structured government procurement; and the pace of the market against the timescales of formal evaluation.\u0026nbsp;\u003cbr\u003e \u0026nbsp;\u003cbr\u003e You will report directly to our Chief Engineering and Products Officer, who leads our most senior customer relationships in this domain.
