About Hyperlayer

Hyperlayer is the intelligent banking platform built for the agentic economy: the financial control layer that sits above banks' existing cores, enabling next-generation Smart Accounts, without ripping anything out. From a single integration, we give financial institutions a secure rules and orchestration engine that lets them design, launch and scale hyper-personalised products in weeks while preserving stability, compliance and control. And there's nothing like us anywhere in the world. 

Hyperlayer works with Tier 1 and Tier 2 FIs across the UK, US, EMEA and Hong Kong, with an award-winning UK consumer app (HyperJar) sitting in the group. We're creating the fintech category that every bank in the world needs: programmable, governed, agent-ready accounts. Your job is to make sure our audiences know that.

We’re Growing Our AI Team 🚀

Hyperlayer is on a mission to reinvent how people and businesses move money, and we need a Principal AI

Engineer with big ideas to help us make it happen. This isn’t just about writing code; it’s about building the AI

infrastructure for the future of payments.

You’ll take the lead on how our engineers actually build software — treating the tools they use to ship code as products in their own right, with a real user experience worth measuring and improving. If you’re excited about reshaping how engineering teams work day to day, you’ll fit right in.

What you'll do

• Define and evolve how our engineering team builds software with AI coding agents — from initial spec through to review, deployment, and monitoring
• Horizon-scan and benchmark emerging open-source coding harnesses and open-weight models, and lead their introduction with enterprise-grade controls — security review, access management, and audit trails
• Extend AI-assisted development into QA and DevOps: automated test generation, code review, CI/CD, deployment, and production monitoring
• Build the feedback loop for our coding agents - capturing engineer satisfaction and outcomes per session, then using that data to improve the tools, prompts, and rules we ship
• Own the steering rules, prompts, and guardrails that shape how coding agents behave across the engineering team, keeping humans in the loop on the decisions that matter
• Evaluate and select AI coding tools and frameworks, and build the internal benchmarks that back those calls
• Participate in system level design and architecture decisions with your peers
• Make sure our AI systems scale, stay reliable, remain secure, and meet financial regulation objectives
• Mentor engineers as they adapt to a new way of building software, sharing what’s working and what isn’t
• Shape the future of engineering at Hyperlayer - your approach to how we build will influence the roadmap.

Qualifications

• 8+ years’ experience in software engineering, including recent hands-on work adopting AI coding agents into a real engineering workflow
• Experience designing structured, spec-driven or workflow-driven processes for AI-assisted development — requirements, planning, implementation, and review
• A track record of building internal tooling, evaluation frameworks, or benchmarks to measure and improve engineering productivity or developer experience
• Experience benchmarking open-source tools or open-weight models against proprietary alternatives, and assessing them for safe enterprise adoption
• Comfort with cloud platforms (AWS mainly, GCP is a plus) and container tech (Docker, Kubernetes)
• Experience extending AI-assisted workflows into QA and DevOps: automated testing, code review, CI/CD, deployment, and monitoring
• Solid Python skills, and comfort defining the rules, prompts, and guardrails that both agents and engineers work within
• A data-driven mindset - comfortable instrumenting a workflow, defining metrics, and using data to improve it, not just building the thing itself
• Understanding of the security, compliance, and audit implications of AI-assisted engineering in a regulated environment
• Strong communication and collaboration skills
• Curiosity and a love for experimentation, always exploring what’s next in how engineering teams build software with AI

Bonus Points For

• Contributions to or hands-on use of spec-driven or multi-phase development frameworks for AI coding agents (e.g. specification-first pipelines, structured agent workflows)
• Knowledge of evaluation frameworks and fine-tuning techniques.
• Experience building or operating an analytics loop for a developer tool — session-level feedback, usage telemetry, and iteration based on it
• Familiarity with agent-to-agent or tool-integration protocols (Model Context Protocol and similar)
• Experience running multiple coding agents or IDEs (Claude Code, Cursor, GitHub Copilot, Kiro, Amazon Q Developer, or similar) and defining consistent rules across them
• Experience running open-weight models in production or self-hosted environments, and standing up the governance — access controls, audit, data handling — needed to bring third-party AI tooling into a regulated enterprise
• Background applying AI agents to security scanning, dependency checks, or compliance gates within CI/CD
• Understanding of security and privacy in AI workflows (encryption, anonymization, compliance).
• Awareness of bias, safety, and human-in-the-loop considerations when deploying autonomous or semi-autonomous coding agents

(You don’t need every skill. If you’re passionate about building the future with AI, we want to hear from you.)
