Technical Lead – Core Services (Blockchain Applications)

We are looking for an experienced and technically-minded Product Owner to lead the product backlog and delivery priorities for a next-generation blockchain core services solution. This role bridges business objectives with technical execution, working closely with architects, engineers, and commercial stakeholders to drive value in a complex, multi-cloud, multi-ledger environment.

While our offices are based in London (UK) and Zug (Switzerland), we welcome applications from qualified candidates across Europe.

The platform is being built as a modular, containerised, microservices-based system to host identity, signing, tokenisation, wallet, and smart contract services with a multi-tenant, multi-chain delivery model. The ideal candidate will bring a deep understanding of product lifecycle management in modern PaaS environments and be able to work across cloud, blockchain, and enterprise integration domains.

Key Responsibilities

• Product Ownership:
• Own and prioritise the product backlog in collaboration with the Programme Manager and Technical Architect.
• Translate stakeholder needs into well-defined technical user stories and acceptance criteria.
• Serve as the voice of the customer and internal users across the product lifecycle.
• Technical Stewardship:
• Understand and communicate core capabilities, including blockchain abstraction layers, multi-tenant architecture, and containerised microservices.
• Collaborate closely with DevOps, SRE, and engineering to ensure smooth CI/CD, observability, and operationalisation.
• Cross-Functional Coordination:
• Liaise with security, compliance, and legal to align product delivery with audit, ISO, and regulatory requirements.
• Coordinate cross-domain priorities (identity, tokens, payments, contracts) with application teams.
• Platform Roadmap Execution:
• Track delivery milestones across multi-phase releases and provide input into strategic planning.
• Lead stakeholder reviews and product demos at the end of each sprint.
• Marketplace & Partner Integration:
• Define onboarding workflows and support structures for third-party developers and partners.
• Ensure documentation, SDKs, sandboxes, and developer tooling are aligned with usage goals.

Technical Domains You’ll Work With:

• Cloud-native infrastructure (Kubernetes, Helm, Argo CD, GitOps, Terraform, Vault/HSM)
• Microservice-based PaaS (API Gateway, RBAC, SSO, CI/CD, observability stacks)
• Multi-chain blockchain architecture (BSV, Ethereum, Hyperledger, Polkadot via adapters)
• Identity and access systems (OIDC, OAuth2, DID/VC, SCIM, RBAC)
• Token and wallet APIs (STAS, ERC standards, multi-sig custody, gas/miner fee engines)
• Event-driven systems and message brokers (NATS JetStream, Prometheus, Loki, OpenTelemetry)
• Compliance frameworks (GDPR, ISO/IEC 27001, 20000), fee engines, and multi-tenant billing systems

Requirements:

• 5+ years in product ownership or technical product management, ideally in a SaaS or PaaS environment
• Proven experience working on infrastructure-heavy or platform-level products (e.g. cloud-native stacks, developer platforms)
• Strong understanding of APIs, containerised services, identity management, and blockchain concepts
• Familiarity with DevOps workflows, CI/CD pipelines, observability tools, and backlog grooming
• Excellent communication skills, especially in cross-functional and technical teams
  

Nice-to-Have:

• Previous experience in a regulated environment (e.g. fintech, healthtech, govtech)
• Experience managing developer portals, SDK rollouts, or marketplace onboarding
• Background in digital identity, smart contracts, or decentralised systems
• Certifications in Scrum, Product Ownership, or Agile delivery frameworks
