Your responsibilities

• Design and build full-stack features: You’ll own problems end-to-end, collaborating closely with product managers, designers, and other engineers to ship scalable, user-facing features with real impact
• Maintain and improve systems: You’ll take shared ownership of our existing systems, ensuring they stay performant, maintainable, and reliable as we grow
• Ensure code quality and clarity: You’ll participate in thoughtful code reviews, contribute to architectural decisions, and help raise the bar for engineering excellence across the team
• Collaborate cross-functionally: You’ll work closely with teammates across disciplines to ensure we’re solving the right problems and delivering real value to users
• Adapt and grow: You’ll stay curious and keep up with evolving tools and technologies—learning quickly and applying new skills when needed
• Participation in our on-call rotation: You’ll ensure the reliability and availability of our services by being available to join the team’s shared on-call rotation as needed

Qualities we look for

• Strong product engineering mindset: You care deeply about solving real user problems and balance pragmatism with technical rigor when designing systems
• Full-stack fluency: You’re comfortable working across the stack, even if your strengths lean more towards backend or frontend. You have solid foundations in system design, and you understand how to ship production systems
• Engineering foundations: You have strong software engineering skills—clean abstractions, robust data modeling, sound architectural decisions—and know how to make things scale
• Collaborative communicator: You’re a clear communicator, active listener, and team player. You thrive in a collaborative environment and welcome feedback
• Growth-oriented: You’re eager to learn, open to new challenges, and not afraid to work with unfamiliar languages or tools when the problem demands it

What we offer

• Diverse and internationally distributed team: joining our team means becoming part of a large, global community with people of more than 90 nationalities.
• Open communication, regular feedback: as a language-focused company, we value the importance of clear, honest communication.
• Hybrid work, flexible hours: we offer a hybrid work schedule, with team members coming into the office twice a week.
• Monthly full-day hacking sessions: every month, we have Hack Fridays, where you can spend your time diving into a project you’re passionate about.
• 30 days of annual leave: we value your peace of mind. With 30 days off and access to mental health resources, we make sure you’re as strong mentally as you are professionally
• Competitive benefits: just as our team spans the globe, so does our benefits package.
