Responsibilities

• Write detailed, comprehensive test cases and test plans aligned to product and business requirements
• Design, develop, and execute automated test scripts; conduct manual investigations to diagnose and resolve backend user-reported issues
• Perform root cause analysis on failing test scripts and production defects — document findings and drive resolution
• Identify coverage gaps in the existing test suite and expand coverage through targeted supplementary scripts
• Lead exploratory testing on unreleased features, including defining requirements, expected behaviors, and downstream impacts
• Integrate automated tests into CI/CD pipelines as mandatory quality gates that block non-conforming code from merging
• Establish and maintain QA standards, documentation, and best practices across the engineering organization
• Work closely with engineering and product teams to ensure product reliability, stability, and a consistent user experience

Requirements

• A minimum bachelor's degree in Computer Science, Engineering, or a related field
• 5+ years in QA engineering with at least 2 years in an architect or lead capacity
• Strong proficiency in test automation (Selenium, Playwright, Cypress, or equivalent)
• Solid coding skills in Python, Java, TypeScript, or similar
• Deep experience integrating tests into CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI)
• Proven ability to define and enforce QA quality gates pre-merge
• Strong analytical and root cause analysis skills
• Excellent cross-functional communication with developers and product managers

We are seeking an experienced Backend Engineer to design and build high-performance, low-latency backend systems. This role focuses on distributed architecture, system reliability, and production excellence in a regulated environment.

Key Responsibilities

Build and scale backend systems
Design, develop, and maintain scalable, high-performance backend services using performance-oriented languages such as C/C++, Go, Rust, or Java.

Optimize performance and reliability
Continuously profile, benchmark, and optimize systems with a focus on latency, throughput, memory efficiency, and correctness in production environments.

Design distributed architectures
Develop and operate resilient, scalable distributed systems, including APIs, data pipelines, and event-driven services leveraging messaging/streaming platforms (e.g., Kafka, Pulsar, RabbitMQ).

Ensure system reliability and operational excellence
Strengthen system security, availability, and scalability in line with regulatory and enterprise standards. Participate in incident response, root cause analysis, and continuous improvement of system resilience.

Cross-functional collaboration
Work closely with product, infrastructure, and data teams to ensure seamless integration across the broader platform.

Maintain engineering excellence
Contribute to code reviews, technical design discussions, and architectural decisions to uphold high standards in code quality, performance, and maintainability.

Requirements

• Minimum 5 years of backend development experience, with strong proficiency in at least one of the following: Go, Rust, Java, or C++
• Strong foundation in algorithms, data structures, concurrency, and memory management
• Proven experience building low-latency, high-throughput systems
• Hands-on experience troubleshooting production systems in Linux environments, with strong ownership of system performance and correctness
• Solid understanding of network protocols (TCP/UDP), and familiarity with WebSocket and HTTP/2
• Experience leveraging AI-assisted development tools (e.g., Cursor, Claude Code) to improve engineering productivity
