If you’re looking for a role where you can work across the stack - from frontend to backend to infrastructure - this is the team for you.

If you want to have a meaningful impact, work on a highly integrated system, and grow your skills across the stack, we’d love you to join!
How we work
- Scrum Development. We embrace Scrum as our framework to foster agility, collaboration, and continuous improvement. Our Scrum team includes a Certified Scrum Product Owner (CSPO) and a Certified Scrum Master (CSM), ensuring a structured yet adaptable development process.
- Domain-Driven Design. We prioritize Event Storming as a core practice to explore and understand complex business domains. By mapping domain events, we gain a shared understanding among engineers, product managers, and stakeholders, allowing us to identify key business processes and constraints early. This event-driven approach helps us design systems that accurately reflect real-world behaviors and evolve alongside our business.
Our Culture
- Product Driven. We focus on solving our users’ issues, not just writing code. Our discussions are always centered around our customers’ needs. We value quick iterations and rapid feedback loops to continuously refine and improve our product.
- Creative + Innovative. We encourage our team to go beyond solving our users’ immediate problems. Until now, our best features have come from implicit or hidden information within user feedback. We look at feedback from many angles to discover our users’ underlying needs and produce compelling features that achieve high user satisfaction. To support rapid feature development, we have a solid testing infrastructure.
- End to End Ownership. Every team member can shape the product and contribute to its success. Our engineers practice end-to-end ownership in their work, from design to implementation and monitoring. We believe in continuous improvement, proactively refactoring and enhancing our architecture to keep it scalable and maintainable. Ultimately, we take ownership not just of the code, but of the impact we deliver to users.
- Documentation. We believe that well-written documentation is a reflection of clear thinking. Whether it’s API specs, architectural decisions, or onboarding guides, we document knowledge to ensure clarity, alignment, and long-term maintainability. Clear documentation empowers our team, accelerates onboarding, and enables us to scale efficiently.
- Blameless Retros. We value continuous improvement of processes, creating a supportive and open work environment. We prioritize learning and improvement over blame. We always seek to enhance our processes through honest and constructive discussions.
