• Design, develop, test and maintain core C++ platform components used across Vay • Build and improve system level tooling for health management, telemetry and incident handling • Own performance profiling and optimization across vehicle and remote driving compute • Contribute to the evaluation and selection of compute hardware for vehicles and remote driving stations • Improve and extend hardware in the loop test setups to accelerate feedback cycles • Support the production fleet in Berlin and Las Vegas on a scheduled basis • Collaborate closely with autonomy, systems and fleet teams to ensure safe and scalable deployments

• While your primary focus will be on ClickHouse, your daily priorities will be shaped by our product goals. • Your day might involve tackling critical ClickHouse bugs that impact our customers or developing exciting new features. • You'll also collaborate with team members to find optimal solutions for various ClickHouse challenges. • We engage in daily discussions about the product, balancing immediate challenges with long-term vision.

• Design, develop, and maintain backend services and APIs using Ruby on Rails. • Implement new features for the SaaS platform, write clean and maintainable code, and ensure the scalability and performance of the application. • Contribute to backend architecture decisions, improve system scalability, and optimize database queries and search performance using Elasticsearch. • Collaborate with product, frontend, and DevOps teams to deliver high-quality features. • Participate in code reviews, maintain testing standards, contribute to CI/CD processes, and support best engineering practices within the team.

Role Description - Has ability to write secure code in Java, J2EE, Oracle, Spring, Jbpm, familiar with secure coding standards (e.g., OWASP, CWE, SEI CERT) and vulnerability management. - CI/CD with Ansible knowledge shall be a plus for the candidate. - Understands the basic engineering principles used in building and running mission critical software capabilities (security, customer experience, testing, operability, simplification, service-oriented architecture). - Understands internals of operating systems (Windows, Linux) to write interoperable and performant code. - Able to perform debugging and troubleshooting to analyse core, heap, thread dumps and remove coding errors. - Understands and implements standard branching (e.g., Gitflow) and peer review practices. - Has skills in test driven and behaviour driven development (TDD and BDD) to build just enough code and collaborate on the desired functionality. - Understands and implements Application Programming Interface (API) standards and cataloguing to drive API/service adoption and commercialization. - Has skills to author test code with lots of smaller tests followed by few contract tests at service level and fewer journey tests at the integration level (Test Pyramid concept). - Apply tools (e.g., Sonar, Zally, Checkmarx) and techniques to scan and measure code quality and anti-patterns as part of development activity. - Has skills to collaborate with team and business stakeholders to estimate requirements (e.g., story pointing) and prioritize based on business value. - Has skills to elaborate and estimate non-functional requirements, including security (e.g., data protection, authentication, authorization), regulatory, and performance (SLAs, throughput, transactions per second). - Has skills to orchestrate release workflows and pipelines, and apply standardized pipelines via APIs to achieve CI and CD using industry standard tools (e.g., Jenkins, AWS/Azure pipelines, XL Release, others). - Has skills to understand, report, and optimize delivery metrics to continuously improve upon them (e.g., velocity, throughput, lead time, defect leakage, burndown). - Has skills to document and drive definition-of-done for requirements to meet both business and operational needs. - Understands how to build robust tests to minimize defect leakage by performing regression, performance, deployment verification, and release testing. - Has skills to conduct product demos and co-ordinate with product owners to drive product acceptance signoffs. - Has skills to understand customer journeys and ensure a Mastercard good experience by continuously reducing Mean time to mitigate (MTTM) for incidents and ensuring high availability (99.95% as a starting point).
