Proof of work

The team

The Growth Engineering team builds the experiences that connect people to our ecosystem for the first time — and keeps them coming back. We design and ship the systems behind our marketing funnels, signup and KYC flows, and the key engagement features that help new users fund their accounts and explore our products. It’s a team with direct influence on company growth, global reach, and user engagement at scale. Our products serve millions of users globally.

How We Work

• We give engineers ownership and trust them to ship high-impact work with craftsmanship and accountability.

• We move quickly, experiment often, and learn fast from data and feedback.

• We work asynchronously across time zones, supporting each other with open communication and shared goals.

Why This Role Matters

Every feature you build will have a visible impact on how people discover, trust, and engage with our products globally. The Growth Engineering team operates at the intersection of product, marketing, and infrastructure — turning ideas into measurable results. If you’re an engineer who enjoys solving business problems through code and believes engineering excellence drives growth, this role is built for you.

The opportunity

As a Senior Software Engineer within Growth Product team, you’ll take on complex, high-impact problems that blend product thinking and engineering excellence. You’ll work across web and mobile platforms, collaborating with design, data, and product teams to deliver features that drive measurable business outcomes. This is an ideal role for engineers who use their technical skills to create real‑world impact — translating high‑level business goals into engineering solutions that improve activation, retention, and monetization worldwide.

• Partner with product managers, designers, and analysts to identify growth opportunities and turn them into high‑quality, data‑driven engineering solutions.

• Implement reusable services and components that power marketing campaigns, onboarding, KYC, and first‑funding experiences across web and mobile.

• Collaborate on distributed systems that handle large volumes of global traffic while maintaining high performance and reliability.

• Participate in design and architecture discussions, balancing user impact, scalability, and maintainability.

• Measure, experiment, and iterate — using data and experimentation frameworks to understand what drives user behavior.

• Uphold and improve engineering standards, performance, and security practices across the stack.

Skills you should HODL

• 5+ years of software engineering experience, including building and maintaining production systems at scale.

• Proficiency in building full‑stack applications using one of the following: TypeScript, Rust, Go, Python, or Ruby, and React or React Native.

• Understanding of distributed systems, performance optimization, debugging, and secure software design.

• Familiarity with infrastructure and tooling such as Docker, Kubernetes, Terraform, MySQL/MariaDB, Redis, or GitLab CI/CD.

• A product mindset — you care about how your work moves key metrics, not just about the code itself.

• Ability to operate autonomously in a globally distributed, remote‑first environment.

Nice to haves

• Experience with A/B testing, analytics instrumentation, or experimentation platforms.

• Background in growth engineering, user funnels, lifecycle, or conversion optimization.

• Familiarity with data analysis tools or experimentation frameworks.
