See yourself in our team

We are seeking a Software Engineer who is passionate about building impactful products and eager to grow within a Product Operating Model. You will be part of a cross-functional, empowered team, working closely with a Product Owner/Manager and Designer as part of the core product trio. Your role involves contributing to the implementation, testing, and improvement of our products whilst developing your product engineering skills.

We value a "product engineer" mindset - where you care about both the product's success and code quality. We expect you to be a collaborative team member who communicates effectively and is eager to learn and grow.

What You'll Do

· Collaborate as part of a "core trio" (Product, Design, Engineering) to understand business and user problems and help implement solutions.

· Contribute to technical implementation of new and existing features under guidance from senior engineers.

· Participate in the full product lifecycle: from implementation to testing (unit, integration), release, and maintenance.

· Learn about and begin integrating AI-driven solutions into engineering workflows and product capabilities.

· Stay curious about new developments in AI (including LLMs and agentic AI approaches) and learn their practical applications.

· Follow and help maintain high standards of code quality, testing, and documentation.

· Identify opportunities for improvements with guidance from senior team members.

· Embrace change and ambiguity, taking initiative in a dynamic, fast-paced startup environment.

· Adapt across roles and responsibilities as needed to support the team's success.

We're interested in hearing from people who

• Have similar experience in software engineering, preferably building customer-facing products.

• Have solid foundation in modern development practices; good technical coding and testing skills.

• Are interested learning about AI tools, platforms, and agentic AI technologies.

• Have full-cycle engineering experience: hands-on implementation, testing, release, and support.

• Are able to work effectively in collaborative teams with ownership mindset.

• Have good communication skills: able to work effectively with cross-functional partners.

• Are quality-focused: You care about shipping well-tested, maintainable software.

• Have a growth mindset: you love to learn, seek feedback, and continuously improve.

• Are comfortable with startup pace: bias for action and adaptability to ambiguity.

• Solid experience with C#, .NET Core, Next.js, React.js, Typescript, Node.js

• Familiarity with full cycle engineering, including test automation (unit, integration and e2e testing)
