What are we looking for?

We are looking for an experienced Senior Full-Stack Engineer who can design and build end-to-end features across React/React Native frontends and Rails, Kotlin, and Golang backend services. The ideal candidate will be a strong problem solver who can work across the full technology stack, contribute to modernising legacy systems, and make sound technical decisions by balancing complexity, maintainability, and business needs while ensuring reliable and high-quality solutions.

What are you expected to do?

• Design and build full-stack features across our React/React Native frontend and Kotlin/Go/Rails backends.
• Implement robust API integrations following our BFF (Backend for Frontend) patterns.
• Build responsive, accessible user interfaces using our design system.
• Write comprehensive tests and contribute to our strong CI/CD practices.
• Contribute to our user and system observability and monitoring, including being on-call.
• Mentor team members and contribute to engineering standards and best practices.

What are the key relationships that are relevant to the role?

• Engineering Manager and Product Managers within the squad.
• Design/UX team for end-to-end feature delivery.
• Other engineers across the microservices ecosystem (Golang, Rails, Kotlin).
• Platform/DevOps team on observability, monitoring, and infrastructure.
• Engineers across the distributed team in Australia, Portugal, and Vietnam.

You’ll be a great fit if:

• You have 5+ years of professional software development experience.
• You have strong Kotlin skill and hands-on front-end delivery experience.
• You have experience architecting full-stack features end-to-end, including REST/gRPC API design.
• You have experience with database and persistence layer design, including managing schema and data changes over time.
• You have experience with user analytics and data transformation pipelines.
• You have experience with cloud platforms (AWS preferred) and containerisation.
• You have experience writing comprehensive tests, working with CI/CD pipelines, and supporting automated deployment practices.
• You have experience applying AI tooling and creating environments where agents can deliver solutions effectively.
• You have strong communication skills in distributed, async teams and are comfortable moving across different languages and technology stacks.

It would be desirable if:

• You have a strong problem-solving orientation and can judge when a complex solution is warranted and when a simpler one will do.
• You operate with ownership and autonomy in a distributed, async-first team environment.
• You are collaborative, with strong product thinking and attention to craft.
• You are committed to continuous learning and professional development.
• You are comfortable moving across technology stacks and problem domains as a generalist.
• You maintain a consistent focus on user experience and technical quality.

What you gain beyond the role:

• Remote + Hybrid Flexibility: Enjoy the best of both worlds-collaborative office days when it counts, balanced with the freedom to work from home
• Achieve Work-Life Balance and Flexibility: Work in an environment where you're trusted and empowered to work independently, while still having the support you need to deliver your best. Here, flexibility isn't just a perk-it’s how we help you perform at your best, without sacrificing life outside of work
• Open Culture: Your voice matters, we encourage proactive communication and fresh ideas
• Supportive Team: From your very first day to every career milestone, we've got your back-with long-term growth and projects you can truly thrive in
• Learn and Grow: Training, coaching, and international opportunities to level up your skills and career
• Be part of a B-Corp company that puts people and planet first while creating meaningful impact

Please note: This role is remote; however, we require candidates to be based locally in Vietnam. This is to support occasional onsite activities such as team events, client meetings, or equipment handover. Additionally, local residency is necessary for compliance with Vietnam labor laws and employment regulations.
