Senior Software Development Engineer in Test (SDET)

This is Hybrid role (3 days in office /2 days remote)
About the team
The Compliance Surveillance team builds the systems that detect market manipulation and financial crime across millions of client accounts. Our platforms process more than 1 billion order events a day, and their correctness supports regulatory compliance and market fairness.
The role
We are looking for a senior software engineer who specializes in testing and quality. You will design, build, and own the test frameworks and quality infrastructure for our surveillance systems. This is a software engineering role, not a test-writing role. You will write production-quality code, make system design decisions, and own the architecture of how we test, measure, and monitor quality. You will work directly with developers and data scientists, with a direct line to engineering leadership.
What you'll do

Design and evolve a scalable Python/pytest test framework with clean abstractions, fixtures, test data management, and parallel execution
Make system design decisions for test infrastructure, treating it as a long-lived software product with its own architecture, code reviews, and maintainability standards
Build test observability: dashboards, flaky-test detection, failure-trend reporting, and alerting
Develop data quality checks for high-volume pipelines and databases, covering completeness, accuracy, and lineage
Write integration, performance, and contract tests (verifying that services producing and consuming the same event streams stay compatible) for distributed, event-driven systems
Triage failures with development teams and drive root-cause fixes
Raise engineering quality standards across development and data science

Required

Bachelor's degree in Computer Science, Mathematics, Statistics, Physics, or a related quantitative field
5+ years of professional software engineering experience, with strong production-quality Python
Solid software engineering fundamentals: data structures, code review, and system design
Experience designing and building a test framework, or a significant part of one, and maintaining it over time
Deep pytest experience: fixtures, plugins, parametrization, and scaling large suites
Git and CI/CD experience (e.g., Jenkins, GitHub Actions, GitLab CI)
Strong written and verbal communication, with close attention to detail

Strongly preferred

Experience testing data-intensive or distributed systems (pipelines, streaming, databases, APIs), including data quality and lineage tools (Manta, Ataccama, Great Expectations)
Monitoring and observability tools (Grafana, Prometheus, Datadog, ELK)

Nice to have

Performance and load testing (Locust, k6, JMeter)
Contract testing (Pact, schema registries, or similar)
Experience in financial services, trading, or regulated environments

Company Benefits & Perks

Competitive salary, annual performance-based bonus and stock grant
Retirement plan 401(k) with competitive company match
Excellent health and wellness benefits, including medical, dental, and vision benefits. Company paid medical healthcare premium.
Wellness screenings and assessments, health coaches and counseling services through an Employee Assistance Program (EAP)
Daily company lunch allowance provided and a fully stocked kitchen with healthy options for breakfast and snack
Corporate events including team outings, dinners, volunteer activities and company sports teams
Education reimbursement and learning opportunities

The anticipated base salary range for this role is $140,000 to $160,000 per year, based on skills, experience, and location. The offered salary is just part of the total compensation package. In addition to a competitive salary, the company offers both a discretionary cash bonus and a stock award, as well as a wide range of benefits, including healthcare, tuition reimbursement, and more.
