Senior SDET - API Test Engineer

About Us:

MatchMove is a leading embedded finance platform that empowers businesses to embed financial services into their applications. We provide innovative solutions across payments, banking-as-a-service, and spend/send management, enabling our clients to drive growth and enhance customer experiences.

Are You The One?

As an API Test Engineer, you’ll join the core payments engineering team and own the end-to-end test automation for backend microservices and APIs that drive our B2B payment platform. You will work closely with developers, SREs, and product managers to ensure reliability and correctness in every transaction flow.

You will contribute to

• Designing and implementing API-level automated test suites for validating payments, FX, wallet, ledger, and remittance services.

• Driving test execution pipelines as part of our CI/CD ecosystem, ensuring fast feedback and stable deployments.
• Creating contract tests from OpenAPI specifications to validate provider-consumer integration in a microservices architecture.
• Instrumenting and tracking non-functional quality metrics like latency, error rate, and throughput alongside SRE/infra teams.
• Collaborating with backend developers to test concurrency, retries, idempotency, and consistency across distributed services.
• Maintaining test harnesses and automation tooling for schema validation, regression checks, and SLA conformance testing.
• Enabling GenAI-based tooling (e.g., for generating test cases or data fixtures) to improve velocity and coverage — while ensuring test logic integrity.
• Performing root cause analysis and working with engineering teams during incidents or regression failures in production.

• Promoting test-first thinking and shifting quality left through tooling, documentation, and collaborative standards.

Responsibilities

• Build, maintain, and extend automation frameworks using tools such as Postman, REST Assured, Karate, or custom suites.

• Write robust, scalable test scripts covering positive, negative, and boundary scenarios for RESTful APIs.
• Automate pre-deployment smoke tests, post-deployment regression suites, and performance baselines for key services.
• Validate integration points across internal systems (e.g., auth, ledger, risk, FX) and external partners (e.g., banking partners , PSP, service providers).
• Manage and version test cases aligned with evolving OpenAPI specifications and platform SLAs.
• Contribute to observability around test execution — logs, metrics, dashboards, and alerting for failed scenarios.
• Maintain test environments, mock services, and test data setup tools with high repeatability and reliability.

• Work with developers and platform engineers to recommend performance improvements, schema contracts, and test coverage expansion.

Requirements

• Atleast 4 years of experience in test automation with a strong focus on API testing and backend system validation.

• Deep understanding of REST APIs, HTTP protocols, headers, authentication, and response validation.
• Experience with test automation frameworks such as REST Assured, Karate, Postman, or custom CLI tooling.
• Proficiency in scripting or development languages like Go, Java, or Python to build test utilities or harnesses.
• Familiarity with API documentation standards (OpenAPI/Swagger) and automated api contract validation.
• Strong foundation in test design patterns, modular test cases, and reusable assertions.
• Exposure to CI/CD tools such as Jenkins, bitbucket pipelines etc.
• Understanding of distributed system behaviors, asynchronous communication, retries, and service orchestration.

• Detail-oriented mindset with a commitment to reproducibility, traceability, and documentation.

Brownie Points

• Experience testing payment platforms, remittance systems, or financial APIs.

• Familiarity with PostgreSQL or MySQL for data validation and transaction traceability.
• Basic knowledge of performance testing and tools like Locust, Artillery, Jmeter or Gatling.
• Experience using GitOps-style workflows for test definition and promotion.

• Exposure to GenAI-powered testing tools or prompt-based test case/script generation.
