We stand by the idea that ‘source code is a liability, not an asset’, so we do our best to keep things simple, readable and less complex to manage.

We work collaboratively with a shared code ownership mindset to design and implement complex technical projects, balancing speed with quality, learning from our past mistakes, and allowing everyone time to take the challenge they see fit.

The opportunity:

We are looking for a Crypto Engineer to join the Uphold Labs Engineering group. 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.

If you are excited about high-availability requirements, scalability problems, automated workflows, infrastructure orchestration, queueing systems, APIs and protocols like GraphQL and gRPC, Uphold is the place for you!

What you will be doing:

• Building the most powerful, easy to use payment 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.
• Working on integrating with existing blockchains.
• Working on a microservice architecture, aiming for security and scalability.

Required Qualifications:

• Knowledge of fundamental blockchain principles.
• Knowledge of blockchain daemons such as Parity, Geth or Bitcoind.
• Knowledge of Solidity programming.
• Experience in integrating with blockchains.
• Understanding of cryptography, including asymmetric (pub/priv key), symmetric, hash functions, encryption/signatures.
• Experience with Node.js, TypeScript and other frameworks.
• 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.
• Fluent written and oral English skills.

Bonus if you have:

• Experience in working on blockchain projects like DeFi, staking or lightning network.
• 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.
• 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:

• An amazing work environment in a company that continues to grow, driven by extraordinary and passionate people that keep up innovating and challenging more each day.
• An international team, in a cutting edge field, working on the most fascinating projects.
• Growth and career opportunities, and the chance to be proactive and creative.
• A flexible and enthusiastic work environment that offers you snacks, a lot of coffee and other great benefits.
• Open and transparent culture - we get together on a weekly basis to share updates, strategic plans, and engage with each other informally over food and drinks.
• Interesting events that keep you connected with the team and celebrate our success.
