Own the vision and execution for Wise’s connectivity layer: service mesh, ingress, and traffic management primitives that support platform scale and reliability and security.

Service Mesh Architecture & Operations:

Evolve our service mesh capabilities (e.g. routing, service identity, traffic policy, observability, resilience patterns). Drive reliable adoption patterns across a large microservice estate.

Edge & Ingress (Public and Private):

Own and improve our ingress platforms (including Cloudflare), ensuring secure, observable, high-performance access into Wise systems with clear operational controls.

Reliability, Performance & Resilience:

Build and operate highly reliable L4/L7 proxy infrastructure (Envoy and related components). Improve SLOs, latency, capacity management, and incident prevention.

Developer Experience & Enablement:

Create paved paths: automation, templates, tooling, and documentation that make the “right way” the easiest way for product teams.

Security by Design:

Partner with security teams to implement defence-in-depth: network isolation patterns, secure defaults, certificate/identity practices, and platform-level controls that scale.

Team Leadership & Coaching:

Lead, mentor, and grow a team of engineers. Set clear expectations, enable strong technical decision-making, and develop engineers through feedback and opportunities.

Operational Ownership:

Own business-critical systems with a pragmatic approach to operations: on-call health, incident response, postmortems, and continuous improvement.

What do you need?

We recognise that people come from a wide range of backgrounds and experiences. You don’t need to meet every requirement below to apply.

Leadership & Communication:

• Experience leading and managing engineering teams (typically 3–8+), including mentoring and performance support
• Strong stakeholder management: comfortable influencing priorities across teams and aligning on technical direction
• Ability to balance customer outcomes, reliability, and engineering sustainability

Proxying, Traffic Management & Networking Foundations:

• Experience building and operating software-based L4/L7 proxies (e.g. Envoy, Nginx, Apache)
• Knowledge of service-to-service communication concerns: routing, retries/timeouts, load balancing, rate limiting, and observability
• Strong troubleshooting skills across systems and networking (Linux command line, logs/metrics/traces)

Kubernetes & Microservices at Scale:

• Experience operating microservices in a containerised environment, ideally Kubernetes
• Familiarity with service mesh architectures (e.g. Istio/Linkerd concepts), including HTTP routing, identity, and traffic management patterns

Cloud & Automation:

• Broad design and operational experience on public cloud (ideally AWS)
• Strong passion for automation: building and testing tooling that reduces operational toil and improves safety and consistency

Desirable:

• Reading familiarity with Go and/or C++ (writing experience is a plus)
• Kubernetes networking experience (services, ingress patterns, DNS, load balancing fundamentals)
• Networking protocols and concepts from L3 to L7, including application-level concerns
• Backend development experience in Go in a continuous delivery environment

Nice to have

• eBPF-based packet filtering and tooling experience
• Familiarity with transport layer security and certificate management
• Experience with Cilium / Network Policies
• Exposure to security best practices and standards (e.g. PCI DSS, defence in depth, network isolation)
• Interest in international finance, foreign exchange, and payment systems

What does success look like?

• You’re building and maintaining one of the core foundation layers of Wise’s platform: safe, reliable connectivity at scale
• Product teams can ship faster because our ingress and service mesh platforms are dependable, well-documented, and easy to adopt
• Reliability improves over time: clearer SLOs, fewer recurring incidents, faster detection and recovery
• You’ve onboarded effectively, understand the team and tribe vision, and are driving a roadmap that aligns to Wise’s mission and values
• You’re growing a strong team culture: high trust, strong technical standards, and healthy operational ownership

What you get back

• Freedom to define your path to success: you’ll help shape the roadmap and take ownership of outcomes
• Flexibility in how and where you work — we’ll do our best to make it work for your needs
• A high-impact platform space where your work directly enables hundreds of engineers and improves customer outcomes
• The opportunity to lead, mentor, and build systems that operate at global scale

For everyone, everywhere. We're people building money without borders  — without judgement or prejudice, too. We believe teams are strongest when they are diverse, equitable and inclusive.

We're proud to have a truly international team, and we celebrate our differences.

Inclusive teams help us live our values and make sure every Wiser feels respected, empowered to contribute towards our mission and able to progress in their careers.
