hyperexponential - Staff Platform Engineer
Requirements
• Defined the architecture, standards, and patterns for the platform domain over a multi-quarter horizon. Makes high-judgement calls on foundational trade-offs such as build vs buy, depth vs breadth, short-term pragmatism vs long-term coherence and brings the organisation along on those decisions. • Navigating disagreement across senior engineers, architects, and stakeholders to reach durable technical decisions. Comfortable holding a position under pressure, updating it when presented with better evidence, and ensuring decisions stick once made. • Accountability for outcomes that span multiple teams and that they do not personally deliver. Designs systems, standards, and enablement approaches that multiply the effectiveness of the engineers around them, rather than being the primary hands-on contributor to every initiative. • Defined how AI and automation are embedded into the platform at an architectural level not just experimenting with tools, but establishing patterns that make AI-augmented workflows the default for engineering teams across the organisation. • Understanding of the adoption dynamics, internal customer needs, and the systemic barriers to self-service. Shapes the platform roadmap based on feedback, usage data, and a clear-eyed view of where friction exists and ensures the platform earns its adoption rather than mandating it. • Identified architectural, security, and operational risks before they become incidents. Influences how the broader engineering organisation thinks about reliability, security posture, and cost efficiency not just within Platform's direct remit. • Connecting platform decisions to business outcomes clearly and credibly. Can represent the platform strategy to senior leadership, translate engineering constraints into business language, and use commercial context to sharpen technical priorities. • Actively developing senior engineers through technical challenge, honest feedback, and deliberate exposure to harder problems. Recognised as someone who raises the capability of the team, not just the quality of the code. Models the engineering culture the organisation is trying to build. • YOU'RE UNLIKELY TO THRIVE HERE IF • You prefer executing predefined tasks over taking ownership of ambiguous problems that require exploration, experimentation, and iteration to solve • You view platform engineering as building infrastructure in isolation rather than treating it as a product with internal customers whose adoption and satisfaction drive success • You're uncomfortable with rapid change and continuous improvement, preferring stability and established patterns over evolving practices based on data and feedback
Responsibilities
• Establish a coherent 12–18 month technical direction for the platform, with clearly articulated trade-offs, milestones, and alignment across engineering leadership. The roadmap is understood, trusted, and actively referenced by stakeholders. • Platform capabilities are adopted broadly across engineering, not because teams are told to use them, but because they are well-designed, well-documented, and genuinely reduce friction. Measurable reduction in Platform as a bottleneck for common provisioning and deployment tasks. • Define the architectural patterns and standards that enable autonomous and AI-augmented workflows across the organisation. Other engineers can build AI-native capabilities without requiring Platform's direct involvement in every initiative. • Platform defined standards for security, reliability, and operational excellence are embedded into how all teams build not enforced through gatekeeping, but adopted because they are the path of least resistance. Measurable reduction in misconfiguration, security exceptions, and operational incidents across the estate. • Senior engineers are visibly stronger for having worked alongside you. The team develops better instincts for architecture, trade-offs, and platform thinking. You are sought out as a technical authority.
