About us and the Team
Tokenovate provides software solutions for capital markets. Using hybrid cloud and blockchain technology, Tokenovate delivers an asset class-agnostic lifecycle platform enabling tokenisation of assets, digital custody, issuance and distribution, collateral mobility for margin and settlement, and automation of post-trade workflows.
Our vision is to simplify trade through a secure, compliant and scalable platform that reduces cost and friction, increases operational efficiency and transparency, and mitigates overall risk. We aim to become a global market leader in financial market infrastructure technology.
We are a UK-based start-up at an early but well-funded stage of development. We are transitioning from product build into commercial launch and customer operation. Our team blends in-house technical leadership with trusted nearshore engineering capability, united by shared energy, empathy and purpose. We work closely, move quickly, and value hands-on problem-solving, ownership and collaboration over hierarchy.
Our offices are in Cambridge Science Park and the City of London.
NO AGENCIES.
The Role
We are looking for a Principal Platform Engineer to provide deep technical leadership across Tokenovate’s cloud platform.
This role is responsible for the technical integrity of our AWS, EKS, GitOps and CI/CD platform. You will review and harden the existing baseline, guide remaining platform build work, mentor engineers, set technical standards and ensure the platform can support secure, reliable and repeatable customer environments.
This is a hands-on senior engineering role. It is not a people-management role, but it carries significant technical leadership responsibility. You will be expected to lead by judgement, example and engineering quality.
The role is suited to someone who has designed, built and operated production-grade cloud-native platforms, preferably in SaaS, fintech or regulated environments.
NOTE that this role is Cambridge or London based, with 2-3 days per week in the office.
You must have the right to work in the UK.
Responsibilities
Platform Architecture and Technical Direction
- Own technical direction for the AWS, EKS, Argo CD and GitOps-based platform.
- Review the existing platform baseline and identify risks, gaps and improvement areas.
- Define and evolve technical standards for cloud infrastructure, Kubernetes, CI/CD, observability, security and resilience.
- Guide design decisions for customer environments, shared platform services and deployment models.
- Produce and maintain architecture decision records for key platform choices.
- Prevent brittle one-off solutions by driving reusable, repeatable platform patterns.
