While our offices are based in
London (UK) and Zug (Switzerland),
we welcome applications from qualified candidates
across Europe. If you are based in either of these locations, we do offer a hybrid working model.
We're seeking a senior technical leader to own end-to-end solution design across our new Core Services and our existing products, while supporting new ventures. You'll translate business outcomes into scalable, secure, and operable designs for a modular, containerised, microservices platform running in a multi-cloud, multi-ledger environment. You'll partner closely with product, engineering leads, DevOps/SRE, and commercial stakeholders to de-risk delivery and accelerate value.
Key Responsibilities:
Platform & Solution Design
* Define target architectures, service contracts, data flows, and non-functional requirements across Core Services and product squads.
* Produce ADRs, reference designs, and golden paths for APIs, events, and data.
* Guide engineers through discovery → design → build → rollout for complex initiatives.
Technical Stewardship
* Champion multi-tenant patterns, API-first design, and stateless, horizontally scalable services.
* Ensure smooth CI/CD, observability, and operability in partnership with DevOps/SRE.
* Promote performance, cost, and reliability trade-offs with clear rationale.
Security, Reliability & Compliance
* Embed security-by-design (mTLS/service mesh, secret management, Vault/HSM/KMS).
* Shape resilience patterns (active-active, failover, DR/RPO/RTO objectives) and drive drills.
* Align designs with ISO/IEC and GDPR requirements in collaboration with Security & Compliance.
Cross-Functional Coordination
* Work with Product Owners to break outcomes into epics/stories with crisp acceptance criteria.
* Coordinate dependencies across our core products and services; unblock delivery teams.
* Lead design reviews, stakeholder updates, and demo/readout sessions.
Roadmap & Standards
* Maintain the platform design roadmap; sunset legacy patterns and introduce new standards.
* Curate reusable blueprints, starter repos, and documentation for internal consumers.
* Partner & Customer Solutions
* Support solution shaping for key partners/customers, ensuring fit to platform guardrails.
* Define onboarding patterns for integrations, SDKs, and external developer experiences.
Technical Domains You'll Work With
* Cloud-native infrastructure (Kubernetes, Helm, Terraform, GitOps/Argo CD, Vault/HSM)
* Platform services (API Gateway, RBAC/SSO, rate limiting, policy enforcement)
* Event-driven integration (REST/gRPC, idempotency, NATS JetStream and/or Kafka)
* Observability stacks (OpenTelemetry, Prometheus, Loki, alerting/runbooks)
* Multi-region resilience (traffic steering, failover, DR testing)
* Data & storage (PostgreSQL/Distributed SQL, object storage/S3, caching/Redis)
* Identity & trust (OIDC/OAuth2, DID/VC, signing flows)
* Tokens & wallets (custody patterns, fee engines, ledger adapters for BSV/EVM/others)
Requirements
Must-Have
* 7+ years leading complex solution/design work for platform or product ecosystems (SaaS/PaaS).
* Hands-on depth with cloud-native microservices, API design (REST/gRPC), and eventing.
* Proven delivery of security-by-design and multi-region resilience patterns at scale.
* Fluency in CI/CD and operability (GitOps, infrastructure as code, SLOs/SLIs).
* Ability to communicate trade-offs clearly to technical and non-technical stakeholders.
* Strong collaboration across product, engineering leads, DevOps/SRE, Security, and PMO.
Nice-to-Have
* Experience with digital identity, signing pipelines, and/or blockchain/ledger adapters.
* Background in regulated environments (fintech/govtech/healthtech).
* Exposure to cost modelling, multi-tenant billing/quotas, and platform productisation.
* Proficiency in Go or Java for prototyping/reference implementations.
* Certifications in cloud, security, or agile delivery.
