The opportunity:
Uphold is looking for a Senior Crypto Engineer to join our Engineering team. This is an incredibly exciting opportunity where you’ll take technical ownership of building and evolving our consumer and business APIs, as well as the microservices powering our web and mobile applications.
You will design, build, and evolve services with three core principles in mind: maintainability, performance, and security — while making informed trade-offs and influencing architectural direction across the platform.
If you are excited about high-availability requirements, complex scalability problems, automated workflows, infrastructure orchestration, queueing systems, and APIs and protocols like GraphQL and gRPC — and enjoy tackling ambiguous, high-impact problems — Uphold is the place for you.
Primary responsibilities:
- Owning and driving the development of the most powerful, easy-to-use payment platform in the world.
- Leading the delivery of complex features and platform enhancements from design through production.
- Making and influencing architectural decisions across crypto services and microservice boundaries.
- Working closely with Frontend and Mobile Engineering teams to define scalable, maintainable integration patterns.
- Collaborating with product managers, designers, engineers, and other stakeholders throughout the full software development life cycle.
- Acting as a technical reference point for the team, helping to raise the bar on code quality, system design, and engineering practices.
- Proactively identifying risks related to performance, scalability, reliability, and security — and driving mitigation.
- Staying current with the evolving tech stack and blockchain ecosystem, and helping guide adoption decisions.
- Writing high-quality, production-ready code with a strong focus on scalability and long-term maintainability.
- Designing and operating secure integrations with existing blockchains.
- Building and evolving a microservice architecture with a strong emphasis on security, observability, and resilience.
Required qualifications:
- Bachelor’s degree in Computer Science, Software Engineering, or a related field.
- 5+ years of professional software engineering experience.
- Strong, hands-on knowledge of fundamental blockchain principles and production blockchain systems.
- Experience operating and integrating with blockchain daemons such as Geth or Bitcoind in live environments.
- Proven experience integrating with multiple blockchains at scale.
- Strong backend engineering experience with Node.js, TypeScript, Go, and/or Python.
- Deep understanding of programming language ecosystems, including performance characteristics and operational trade-offs.
- Strong understanding of relational databases (preferably PostgreSQL) and non-relational databases (e.g. Redis).
- Strong understanding of web semantics, APIs, and distributed systems concepts.
- Experience working with version control systems and modern development workflows.
- Working knowledge of standard development pipelines, including build, test, and deployment automation.
- Fluent written and oral English skills, with the ability to communicate technical decisions clearly.
Bonus if you have:
- Experience working on blockchain projects such as DeFi, staking, Lightning Network, or Layer 2 solutions.
- Experience designing and operating APIs consumed by external teams or partners.
- Solid working knowledge of Solidity and smart contract interactions.
- Experience building event-driven systems using message queues (e.g. Kafka, NSQ, Pulsar, RabbitMQ).
- Experience integrating and operating third-party APIs in security-sensitive environments.
- A proven record of working with performance budgets, SLAs, or SLOs.
- Strong domain fluency in cryptocurrencies or other digital assets.
- Public speaking experience, technical writing, certifications, or blog posts.
- Open-source contributions, including tooling, libraries, or meaningful fixes to existing projects.
What we offer:
- Innovation and Impact: Contribute to pioneering projects in a dynamic and challenging environment.
- Competitive Compensation: Stock options, performance bonuses, and comprehensive benefits on top of a competitive salary.
- Strong Company Culture: Thrive in a supportive, collegiate environment with values of integrity, teamwork, accountability, and excellence.
