The NHS workforce is broken. Clinician burnout is at an all-time high. The UK's temporary staffing bill has hit £8 billion. The way healthcare organisations manage and schedule their workforce is failing.
We built Lantum because we want to change that. Our Connected Scheduling™ platform helps healthcare organisations manage their workforce more effectively, giving clinicians more control over how and when they work and giving organisations the tools to staff more efficiently. Over 50% of UK GP practices and 30% of UK Trusts already rely on us. We've saved the NHS millions and helped thousands of clinicians improve their work-lives. We're rebuilding how this industry operates and we're looking for people who want to be part of that.
Lantum’s market-leading Connected Scheduling™ platform keeps the NHS staffed. In Primary Care, it rosters clinicians across more than 2,000 organisations, with digital staff banks and a marketplace of 30,000 vetted clinicians. In Secondary Care, In-Genius™ builds optimal rotas for resident doctors, In-Flight™ manages them day to day, and In-Check™ Compliance (formerly DRS) audits every worked hour against working-time legislation and NHSE standards so that payroll is exact.
About the Role
As our Principal Engineer, you will lead all core software engineering work across the entire Lantum platform and service architecture to scale Lantum’s next stage of growth. You will work alongside our heads of AI/ML and product, healthcare domain experts, and Operations teams while staying hands-on to ship code to production yourself. The role is a true full-stack - “any-stack” - one, and covers back-end, front-end, architecture, infrastructure, DataOps, AI SDLC, and security realms and disciplines.
Responsibilities
As a Principal Engineer,
● you own core, end-to-end software engineering processes and infrastructure;
● you ensure that our existing core revenue-generating systems run without interruption under strict SLAs while optimising them, expanding their capabilities, and increasing cross-connectivity across our multi-product and services platform;
● you protect sensitive operational healthcare data and financial information (as both assets and end-to-end data flows), and ensure that all systems, services, and artefacts meet strict regulatory criteria pertaining to security, observability, traceability, and verifiability;
● you lead, support, and guide other engineers while synchronising build horizons with our wider multidisciplinary team;
● design, build, operate, and secure agentic workflows, multi-agent systems, guardrails, security-first agentic architectures and topologies, and context flows;
● you operate, optimise, and govern coding agents, software factories, and the use of wider AI tooling to enable reliable and precise AI FinOps and effective AI governance; and
● you operationalise and optimise the next stage of Lantum’s AI-native software development lifecycle that combines agentic loops with rigorous verifiability, observability, testing, and review processes.
About You
The Principal Engineer role is ideal for an engineer archetype who
● has a true full-stack (“any-stack”) and polyglot mindset;
● has a track record in building successful, mission-critical systems in non-trivial domains such as healthcare, finance, insurance, aviation, cybersecurity, and the like;
● has (ideally) operated in both agile start-up environments and large(r) formal, regulated enterprises;
● is an inspirational tech lead, leader, and catalyst, with a passion for guiding, supporting, and growing engineering organisations; and
● is a true builder with deep passion for robust end-to-end software engineering, with deep expertise in the traditional praxis, and, ideally, the new, emerging AI SDLC and agentic praxis.
Requirements
Direct, demonstrable expertise and a track record in:
● owning (designing, building, deploying, scaling, optimising, operating, and maintaining) and signing off non-trivial systems, services,…
