The opportunity:

Uphold is looking for a Senior Quality Assurance Analyst to join our Enterprise APIs Engineering team.

This role sits at the heart of Uphold’s core financial platform, working on the Enterprise APIs that power critical payment, trading, and investment flows used internally and by external partners. These APIs are fundamental to how value moves through the Uphold ecosystem, making quality, correctness, and predictability essential.

You will be responsible for validating product functionality directly at the API layer, ensuring that business requirements are correctly implemented, contracts are respected, and financial flows behave reliably across distributed services.

This is a senior, hands-on QA role with a strong focus on API testing, close collaboration with backend engineers, and active involvement in improving automated test coverage and API reliability.

What you'll focus on:

Testing and validating REST APIs that support core financial, payment, and investment functionality.
Ensuring business requirements are correctly implemented at the API level, including validation of edge cases, error handling, and failure scenarios.
Designing and executing API test scenarios to validate:
- business logic and data integrity authentication and authorization (OAuth2 / JWT)
- idempotency and consistency
- asynchronous behaviors (webhooks, callbacks, event-driven flows)
Working closely with Engineering throughout the development lifecycle, from requirement review to production validation.
Reviewing API specifications, contracts, and technical designs to identify risks and test considerations early.
Performing exploratory and manual testing across API and, when relevant, UI layers.
Clearly documenting defects so they can be reproduced and resolved efficiently.
Creating and maintaining test documentation, logs, and reports for API testing activities.

Automation and quality improvement

Working with existing automated API test suites, including reviewing test results and reports.
Contributing to the expansion of automated test coverage, particularly for REST APIs and end-to-end financial flows.
Collaborating with engineers to identify gaps in automation and opportunities to improve reliability and confidence in releases.
Helping evolve QA practices, processes, and quality standards within the Enterprise APIs domain.

Required qualifications:

Degree in Computer Science or a related field, or equivalent practical experience.
8+ years of experience in QA or software testing, with a strong focus on testing APIs or backend systems.
Solid experience testing REST APIs, using tools such as Postman, Bruno, or similar.
Proven ability to validate:
- API contracts and schemas
- business rules and edge cases
- authentication and authorization flows
- error handling and idempotent behavior
Experience testing asynchronous or event-driven processes (e.g. webhooks).
Exposure to API or functional test automation using tools such as Newman, Postman collections, Cypress, or similar frameworks.
Strong exploratory testing skills and a risk-based testing mindset.
Ability to assess quality priorities based on product context and customer impact.
Experience working in agile or lean development environments.
Fluent written and spoken English, with clear communication skills.
Strong attention to detail, analytical thinking, and problem-solving ability.
A proactive mindset, with a genuine interest in improving product reliability and quality.

Bonus if you have:

Experience with one or more programming or scripting languages.
Deeper experience designing or maintaining automated test frameworks.
Experience working in fintech, payments, trading platforms, or other regulated environments.
Ability to analyze business requirements and translate them into effective API test scenarios.
Curiosity and continuous learning around modern testing practices and tools.

What we offer:

Innovation and Impact: Contribute to pioneering projects in a dynamic and challenging environment.
Competitive Compensation: 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.
Global Collaboration: Participate in regular updates, strategy sessions, and networking opportunities across the group.
Development Opportunities: Access training and mentorship programs.
Flexibility: Enjoy options to work from home, other locations, or adjust your hours.
Inclusive Environment: Value and respect diverse perspectives.

Benefits:

Annual bonus program based on individual, team and company performance.
Home office stipend for a productive setup.
Generous PTO, healthcare, and employee assistance programs.
Engaging events and celebrations.
Well-stocked office kitchen with a foodie culture.
