• Bachelor's degree in Computer Science or any suitable combination of education, experience, and training.
• At least 5 years of experience in object-oriented backend development using languages such as C# or Java, with interest and openness to transition into Python or GO.
• Familiarity with performance/load testing tools like Locust, k6, Gatling, or JMeter.
• Deep experience developing and maintaining comprehensive automated test suites, including unit, integration, and performance tests, to ensure system resilience and scalability.
• A strong track record of mentoring engineers, leading code and design reviews, and driving high-impact technical decisions across cross-functional teams.
