Solution Architect (Remote - Work from Anywhere)

Work from anywhere, impact everywhere Diversity is at the heart of who we are at Xapo Bank. We’re a fully distributed team of over 160 Xapiens that work remotely from 50+ countries around the world. Our beginning: A world that enjoys economic freedom and wealth protection,no matter where you live or who is running your country. To achieve that, we search the world for the best people for the job. We work hard, think globally, and inspire each other to learn and grow. We are committed to changing the way things are done. Although we are headquartered in Gibraltar, this is a full time, 100% remote position Work from anywhere! Position overview We’re looking for a Solution Architect to join our engineering function, reporting directly to the CTO. At Xapo, we are building truly cross-functional teams with full ownership of design, architecture, building, testing, delivery, data, and operations, structured as Stream Aligned Teams (SATs), Platform teams and Enabling teams as per Team Topologies. You will collaborate closely with engineering leaders and the SRE function, as well as fellow members of the product, apps, and design. This is a deeply hands-on role. You will not sit on top of an ivory tower drawing boxes and arrows, you will write code, build production-grade Proofs of Concept and demonstrate what good looks like by example. You will own the Architectural Advice Forum (AAF), facilitating decentralised architectural decisions captured as ADRs without becoming a bottleneck or single point of approval. You will be the CTO’s partner on AI strategy, drive standardisation across backend, web and mobile engineering, and work closely with our SRE team on reliability, observability and platform concerns. This is an opportunity to shape how a regulated crypto bank designs, builds and operates software, having a real impact on how the future of finance looks. Responsibilities Own and facilitate the Architectural Advice Forum (AAF), driving decentralised decision-making that is captured as ADRs. The forum is yours, the challenge is expected, but you are not “single” approver of every architectural change, the goal is for decisions to be made as close to the teams doing the work as possible. Personally build production-grade Proofs of Concept to de-risk new patterns, validate architectural ideas and demonstrate “what good looks like” ahead of broader adoption. Partner with the CTO on Xapo’s AI strategy, identifying high-value opportunities, evaluating tooling, prototyping solutions and helping engineering teams adopt AI responsibly across the SDLC and our customer-facing products. Own cross-cutting standardisation across backend, web and mobile engineering, patterns, paradigms, observability, security, testing and delivery, so that quality and velocity scale together. Define and uphold the engineering quality bar across backend, web and mobile, covering testing, code review, observability, security, performance and production-readiness, and lead by example through your own POCs and code reviews Embed Security-First Architecture across everything we build. For a regulated crypto bank, security is not a checkbox or a separate workstream, it is the DNA of our products. You will set the threat-modelling, secure-by-default and defence-in-depth patterns that every team builds against, and partner with our Security function to evolve them as our risk surface grows. Champion Domain-Driven Design and Event-Driven Architecture as foundations for how we model our domain and evolve our systems. Work closely with the SRE team on reliability, capacity, incident response, observability and the evolution of our internal developer platform. Coach and mentor engineers across SATs, platform and enabling teams, leading through inspiration and influence rather than authority, and helping the whole organisation raise its architectural bar. Surface and unblock systemic technical risks, technical debt and cross-team dependencies before they hit production.…
