About Us
OpenFX is on a mission to move money as freely as data, unrestricted by time zones, banking hours, or legacy systems. We are building the infrastructure that will power the next generation of cross-border payment systems for institutions. The team's execution has been exceptional, and we're scaling at a remarkable pace. Our stellar early team comes with experience in companies like J.P. Morgan, Goldman Sachs, FalconX, Paypal, Affirm, Polygon, Kraken, Nium & others. We're backed by Accel, Faction, NfX, Accomplice, and other top-tier investors.
Role Overview
As our systems grow in complexity and volume, we need an SDET Engineer who can go beyond writing scripts to architecting test frameworks that are scalable, stable, and AI-leveraged. You will ensure that our high-velocity deployment pipeline—moving real money—remains robust while reducing manual intervention to near zero. This is a hands-on, high-impact role where you will directly strengthen the reliability of our financial infrastructure.
Key Responsibilities
- Design and optimize high-performance automation frameworks using Java/RestAssured and JS/Playwright
- Own the integration of tests into CI/CD pipelines and manage containerized test environments (Docker/Kubernetes)
- Architect load and stress testing suites using JMeter or k6 to simulate high-traffic financial events
- Establish patterns for the team to use AI (Copilot, LLMs) for synthetic data generation and automated Root Cause Analysis
- Develop complex test scenarios for transaction idempotency, ledger consistency, and financial calculation validation
- Provide technical guidance and code reviews to ensure high standards of clean, reliable code
- Drive 100% automation coverage of critical-path financial flows within the same sprint
- Achieve 40%+ reduction in regression time through parallelization and AI-assisted scripting
What We're Looking For
Required
- 3 to 7 years of experience in SDET or Backend Development roles
- Expert proficiency in Java, JavaScript, or Python
- Proven experience building or significantly extending automation frameworks (RestAssured/Playwright)
- Strong understanding of relational databases (SQL) and API security (OAuth, HMAC signing)
- Expert knowledge of Maven, TestNG, and Git (complex branching/merging)
- Strong fundamentals in Data Structures and Algorithms
Preferred
- Deep familiarity with AWS (S3, CloudWatch, EKS)
- Experience managing test runners in Docker or Kubernetes
- Hands-on experience with JMeter or k6 for load testing
- Proactive use of AI tools to increase engineering velocity
What We Offer
- Competitive salary and benefits package.
- Equity in a rapidly growing company.
- Opportunity to work in a fast-paced startup at the forefront of fintech innovation.
- Opportunity to make a significant impact on global financial infrastructure.
- Collaborative work culture with emphasis on personal and professional growth.
We are committed to building a diverse and inclusive workplace. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.
