About the team:

You will be part of a small, cross-functional, autonomous, distributed team across Europe and Asia in charge of one of the most important components in our app, thus being reliant on by a lot of other functional teams and integral to showcasing their work.

You will have shared time for collaborative activities such as planning, retros, stand‑ups, and brainstorming sessions. Some interesting challenges the teams face are implementing new technologies such as AI, for multiple platforms, and dozens of millions of users. You will be working alongside a team of experienced engineers with high quality mentorship support and help drive you to success, enabling you to become a valuable member of the team and stand on your own.

You will use a broad and modern tech stack with:

• Programming Language: We use TypeScript for Frontend. Our backend services are written in Kotlin.
• Frameworks and Libraries: We use React/Redux and WebAssembly to compile our Swift core logic.
• Monitoring and Logging: We are currently using Datadog for monitoring and logging. Metrics are collected across our agents, taken from the logs using metric filters, and updated directly from lambda function or the application.
• Infrastructure‑as‑Code: Most of our infrastructure is written with Terraform.
• CI/CD: We currently use GitHub Actions for CI, and ArgoCD for CD.
• Deployments: We have multiple EKS clusters set up either for Blue/Green rollouts or dedicated feature sets. We are currently updating these clusters using ArgoCD and Atlantis.
• Our main databases are MongoDB and a self‑managed CockroachDB cluster running on EKS.
• We believe in automating ourselves out of our jobs.

About the role:

This is the role for you, if you’re excited to work on the things listed below:

• Bring our core iOS App to cross platforms i.e. Web, Android and Windows systems, based on scope and requirements, using cross‑platform SDKs.
• Rapidly build prototypes/simulations from mockups, state your assumptions, and iterate with mentor feedback.
• Improve rendering performance and memory optimizations to create a performant UX.
• Support, maintenance and ongoing development for existing applications and projects, owning bug triage rotations that build judgment.
• Unit‑test code for robustness, including edge cases, usability, and general reliability.
• Continuously discover, evaluate, and implement new technologies to maximize development efficiency, leaning into curiosity about multiple languages, runtimes, and tools.
• Shipping Progressive Web Apps (PWA) to various platforms utilising latest technologies, pairing on deployments until you can run the playbook yourself.

The skills you will need to be successful in the above:

• Experience building modern web applications using libraries and frameworks like: React/Redux: through internships, coursework, or personal projects.
• Expertise with TypeScript
• Up to 2 years of related working experience (or equivalent internships) with clear examples of lessons learned.
• Exposure to cross‑platform SDKs or a drive to ship the same experience across devices.
• Familiarity with cloud storage, deployment, and computing concepts; AWS experience is great but curiosity matters more.
• Ability to follow best practices (CI/CD, automated testing, version control) and raise blockers quickly.
• Strong fundamentals in Computer Science or adjacent disciplines, plus an eagerness to keep learning how things work under the hood.
• Excellent problem‑solving, communication, and story‑telling skills.
• Experience building cross‑platform solutions — or at least a tinkerer’s interest in WebAssembly and related cross‑platform technologies.
