Key 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.

Requirements / Qualifications

• 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.

With flexible working hours and trust in your productivity, we are in sync with your team’s general locations and time zones to foster effective and seamless collaboration.

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 and get the opportunity to work with other teams–we value your initiatives, impact, and creativity.

30 days of annual leave: we value your peace of mind. With 30 days off (excluding public holidays) 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. We've crafted it to reflect the diversity of our team and tailored it to align with your unique location, to ensure you feel supported every step of the way. If this role and our mission resonate with you, but you're hesitant because you don't check all the boxes, don't let that hold you back.
