What you'll do

  • Set and own solution architecture on flagship engagements, including bids and the delivery programs that follow them
  • Review critical architecture decisions and act as the counterpart to the client's chief architect
  • Define and enforce engineering standards across the practice: integration patterns, API design, CI/CD and release strategy, non-functional requirements, and estimation
  • Lead technical presales: technical discovery, solution design, effort estimation, and architecture sections of RFP responses
  • Build the technical organisation: hiring architects and senior engineers, growing existing people, deciding what capability to build versus buy
  • Set technical direction beyond the current portfolio, including platforms, domains, partnerships and certifications
  • Lead a distributed engineering team across time zones in Agile or hybrid delivery models

What we're looking for

  • 10+ years in software engineering, with a Java background and a career spent on integration work (ESBs, middleware, API platforms, event-driven systems, service layers over legacy cores)
  • At least two large, multi-year, multi-system programs with architectural responsibility from discovery through production
  • Real exposure to the banking or financial services sector: core banking systems, payment rails, regulatory and audit constraints, security review cycles
  • Deep command of enterprise integration patterns and API design, including where REST stops being the right answer, with a clear position on microservices versus SOA
  • Experience leading distributed engineering teams across time zones, in Agile or hybrid delivery models
  • Ability to sit in front of a bank's architecture review board and hold your ground in English; written and spoken fluency is non-negotiable
  • Comfort with containers and orchestration (Docker, Kubernetes or OpenShift) at the level of someone who has debugged a production deployment

Nice to have

  • MuleSoft or Salesforce experience
  • Hands-on history with other integration platforms: IBM Integration Bus, TIBCO, WSO2, Boomi, Apache Camel, Spring Integration; migration projects off any of them especially interesting
  • Banking and payment standards: ISO 20022, ISO 8583, SWIFT, Open Banking and PSD2, card scheme integrations
  • Identity and access: Keycloak, ForgeRock, Okta, Auth0, and the API security work that goes with them
  • Messaging and streaming at scale: Kafka, RabbitMQ, ActiveMQ, Solace
  • DevOps and observability: Jenkins, GitLab CI, TeamCity, Prometheus, Grafana, ELK, plus cloud on AWS, Azure or OCI
  • Public sector or government delivery experience
  • German or Arabic

Benefits

  • A C-level seat in a company small enough that your decisions take effect the same quarter you make them
  • Two interviews to an offer
  • Relocation support to Cyprus, Germany or Poland if you need it
  • Flexible schedule, and no requirement to sit in an office for its own sake
  • 31 days of vacation, plus 5 sick days
  • Certification and training on whatever platform the role demands, MuleSoft included
