Introducing Masabi

At Masabi, we're driving the fare payment revolution, powering the journeys of millions all over the world. We build fare collection platforms that allow riders to seamlessly buy and present tickets for public transport either on their mobile phones, from a ticket machine, or even by tapping their bank card to travel.

Our Justride platform is used in over 250 locations globally, including some of the largest cities in the world. With our industry-first mobile ticketing SDK, we've partnered with large players in the transport space, including Uber, Moovit and Transit.

Your own journey is important to us too. Choosing a role here means joining a network of innovators from all walks of life; a group of passionate individuals who consistently deliver. Here, you'll find the tools you need to build the career you want. Whether you're taking the direct route or trying a new path, we'll support you no matter what.

The Role_
Masabi is hiring a hands-on, deeply technical Chief Technology Officer to shape the next era of our platform's architecture, innovation, and customer impact.

This role is central to Masabi's strategic direction, combining architectural ownership, technical excellence, and product foresight to drive global transit transformation. For candidates favouring a traditional CTO role, the scope covers the entire Engineering organisation of about 150 people, including development, operations and compliance. However, we are equally open to candidates with a more hands-on technical profile over people and process management.

This flexibility is supported by a strong Senior Director of Engineering who oversees day-to-day team management and a technical Chief Product Officer who can partner on shared responsibilities.

In either model, you'll be our most senior and capable technologist, championing architectural clarity, technical depth, and inclusive, AI-driven innovation. You'll also be a key figure in strategic customer engagements, especially where technology is at the core of the conversation.

Location_
This is a remote-first leadership role, open to candidates in the UK. Some occasional travel may be required for planning sessions, strategic customer engagement, or team events.

Responsibilities_

Technical & Architectural Leadership

Define and continuously evolve Masabi's long-term technical strategy aligned with scalable growth
Take full accountability for platform stability, extensibility and technical integrity
Guide architectural decision-making with clarity and pragmatism
Maintain hands-on connection with our code and systems, leading by example to model engineering excellence

AI Innovation & Product Enablement

Identify opportunities to apply AI/ML/Predictive Analytics across our product suite, internal tools, and operations
Foster a culture of responsible experimentation, AI fluency, and continuous learning

Engineering Culture & Talent Stewardship

Lead, support, and develop our community of Engineers
Champion a culture of excellence, psychological safety, and inclusion
Collaborate cross-functionally across Engineering, Product, Business Development, and Professional Services to align priorities and outcomes

Strategic Business Collaboration

Manage Incident and Problem Management functions to ensure a consistent, high-quality customer experience
Work closely with Product and Business Development to shape impactful platform enhancements
Represent Masabi in strategic customer and partner conversations involving architecture, security, compliance, and integration

Growth, M&A & Compliance Readiness

Lead or support technical due diligence and platform integration during mergers, acquisitions, or strategic partnerships
Ensure platform alignment with compliance standards including SOC2, ISO27001, and PCI
Bring experience navigating technical transformation during periods of significant organisational growth

Our Stack_
At Masabi, we take a modern, pragmatic approach to technology, optimising for scalability, resilience, and developer experience.

Kotlin (Backend & Mobile), TypeScript (Web), Python
KrakenD & Ktor (APIs), Vue/Nuxt (Frontend), Capacitor (Hybrid Mobile)
Fully cloud-hosted on AWS - Fargate, Lambda, DynamoDB, S3, SSM, KMS, etc.
Kafka / Kafka Streams, DynamoDB as the primary store, limited use of Aurora
GitLab CI/CD, Terraform & Terragrunt (IaC), Renovate (Dependencies)
Grafana Cloud for metrics, logs, traces and SLOs; OpenTelemetry as our instrumentation standard
Strong emphasis on meaningful tests at all levels of the testing pyramid

We're intentional about our tooling and open to better ways of doing things; this role will shape where we go next.

About You_

You have extensive leadership experience in software engineering in SaaS and complex B2B environments
You are a hands-on technical leader who remains close to code and architecture while also capable of scaling teams and strategy
You bring expert-level knowledge of distributed systems, cloud-native architecture, and modern, scalable infrastructure

You've successfully embedded AI/ML into production systems, with measurable outcomes in either product or internal efficiency
You're a clear communicator, cross-functional collaborator, and thoughtful leader who thrives in complex, mission-driven environments

Bonus Points_

Experience in mobility, payments, fintech, or highly available enterprise SaaS
Involvement in platform re-architecture, system integrations, or M&A-related transformations
Comfort working in regulated or security-sensitive environments
