Tech Lead (Backend): Cards

• Define and drive the technical architecture for the cards platform (card issuing, tokenization, transaction processing, settlement). - Act as the primary technical decision-maker within the squad, including decisions for card infrastructure components. - Lead the design and delivery of scalable, compliant systems, APIs, and distributed services. - Own the technical roadmap for cards engineering, aligning with product and business objectives. - Coordinate delivery across multiple workstreams (card issuance, transactions, settlements, compliance). - Contribute hands-on to the codebase through development, debugging, optimisation, and code reviews. - Mentor and develop engineers through technical coaching, pairing sessions, and constructive feedback. - Promote engineering best practices around testing, CI/CD, observability, reliability, and security. - Lead technical assessments and integration design with third-party card providers, evaluating their APIs, security posture, and system capabilities to inform architecture decisions

• Remove technical blockers and make trade-off decisions to keep projects on track. - Facilitate collaboration across squads and represent cards engineering in cross-org technical forums. - Partner with Product and Business on prioritisation, translating business requirements into technical solutions. - Drive operational excellence by improving monitoring, incident response, and deployment practices. What we need from you:

• 8–12+ years of professional software engineering experience, including 3–5+ years in senior or technical leadership roles. - Proven track record designing and delivering complex, scalable systems such as microservices, event-driven architectures, or high-throughput APIs

• Experience acting as the primary technical decision-maker for a team or domain, including evaluating trade-offs, selecting technologies, and defining standards. - Strong understanding of card payments, issuing programmes, or transaction processing in a regulated environment. - Enthusiasm for adopting AI-assisted development tooling (e.g, Claude Code, AI code review agents) to accelerate delivery and improve code quality across the squad

• Experience with PCI-DSS compliance or similar security/regulatory frameworks. - Strong experience leading end-to-end delivery of complex initiatives across multiple sprints. - Experience mentoring and developing engineers through coaching, code reviews, and technical guidance. - Strong proficiency in Java/Spring Boot. - Strong understanding of RESTful APIs, system integration patterns, and data modelling using SQL and/or NoSQL databases. - Good understanding of cloud platforms such as AWS, GCP, or Azure. - Experience with containerisation and orchestration technologies including Docker and Kubernetes. - Experience with observability and reliability tooling including logging, metrics, tracing, and performance optimisation. - Strong communication skills with the ability to explain technical concepts clearly to both technical and non-technical stakeholders. - Familiarity with crypto/fiat payment rails and issuer integrations is a plus. - Open to participate in an out-of-hours on-call rota. Nice to have

• Experience working in high-growth or fast-scaling technology environments. - Exposure to fintech, payments, or other high-availability transactional systems. - Experience contributing to engineering strategy, hiring, or organisational scaling initiatives. What you can expect from us:
