We are looking for a Senior Backend Engineer to join our Engineering team. This is an incredibly exciting opportunity where you’ll get to focus on building and improving our consumer and business APIs and the many microservices powering our web and mobile applications. You will be designing and building services with three core principles in mind: maintainability, performance, and security.

What you’ll be doing primarily:

  • Building the most powerful, easy to use crypto onramp and offramp platform in the world.
  • Delivering new features and enhancements to our platform.
  • Working closely with the Frontend and Mobile Engineering teams to integrate frontend UI.
  • Collaborating with product managers, designers, engineers and other project stakeholders throughout the software development life cycle (planning, design, implementation, deployment and support).
  • Helping the team keep up-to-date with the tech stack ecosystem.
  • Writing high quality code with performance and scalability in mind.

Required qualifications:

  • BS or advanced degree in Computer Science or equivalent.
  • Spent lots of quality time coding, deeply learning the powerful idioms and important idiosyncrasies of multiple programming languages and their ecosystems. We like to code mostly in JavaScript (node.js), Python, Golang and C/C++.
  • Strong understanding of relational (preferably PostgreSQL) and/or non-relational databases (e.g. Redis).
  • Strong understanding of web semantics.
  • Knowledge of revision control systems.
  • Basic knowledge of standard development pipelines, including build and other automation tools.
  • Excellent communication skills and a team player with the ability to work in cross-functional teams, and with a great attitude.
  • Fluent written and oral English skills.

Bonus if you have:

  • Experience in developing APIs for other products you’ve worked on.
  • Developing software interacting with message queues (e.g. Kafka, NSQ, Pulsar or RabbitMQ).
  • Experience in integrating APIs from other services providers.
  • Proven record of having worked with performance budgets.
  • Fluency in cryptocurrencies or other digital assets as they are core to our business.
  • Community talks, certifications, and/or blog posts on your interests and research.
  • Open source project contributions of any kind, such as tools developed to solve specific problems you’ve had or fixing issues on existing projects.

Importantly, if you’re looking for a senior role with us, you will have achieved many of the things above while also providing mentorship to others, and have engaged in public speaking opportunities.

What we have to offer you:

  • Innovation and Impact: Be a part of a company driving innovation and making meaningful impact. Work on cutting-edge projects in a stimulating and challenging work environment.
  • Competitive Compensation: We offer a salary, stock options, performance-based bonuses, and comprehensive benefits.
  • Strong Company Culture: Join a supportive and positive work environment built on shared values of integrity, teamwork, accountability, and excellence.
  • Global All-Hands Calls: Regular sessions to share updates, strategize, and foster connections.
  • Development: Opportunities for training and mentorship programs.
  • Flexibility: Work from home, from other locations or slightly different hours available.
  • Inclusive and Diverse Environment: Foster an environment where different perspectives are valued.


  • Annual bonus program based on individual, team and company performance.
  • Home office stipend to support the setup of a productive home office.
  • Generous PTO, healthcare coverage, and employee assistance programs.
  • Interesting and fun events and celebrations.
  • Foodie culture and well-stocked office kitchen.
