Principal Software Engineer

Job Summary Location: Remote North Calorina, Remote Miami, Remote Florida. Division: Ticketmaster, Payments. Line manager: VP Marketplace Engineering. Contract terms: Permanent, full time. Overview We’re seeking an experienced C++ engineer to join our Platform Payments team, working on Ticketmaster’s mission‑critical payment processing systems that handle millions of transactions monthly across multiple payment methods and 20+ gateway providers. The role focuses on maintenance and strategic modernization of a mature C/C++ codebase spanning three decades, with a clear trajectory into systems design, gRPC service architecture, and new technology (Rust). Responsibilities Maintain and strategically modernize high‑throughput payment processing systems handling real financial transactions in real time. Drive platform migration work, including migrating a core Windows C++ authorization gateway to Linux via Clang and Bazel. Develop robust payment integrations with third‑party gateways (Chase Paymentech, Barclays, HSBC, AMEX, Adyen, Braintree, Klarna, Shift4, and others). Decompose legacy IPC frameworks into gRPC services, enabling payment components to be reused across the broader payments ecosystem. Implement security‑critical features involving encryption, PCI compliance, and sensitive payment data handling. Optimize performance of transaction processing pipelines where latency directly affects whether a customer completes a purchase. Incrementally steer legacy codebases toward modern C++ practices (RAII, ownership semantics, safe string handling) without breaking the payment flows that depend on them. Design and implement comprehensive testing, including unit tests, integration tests, and fuzz testing for security‑critical components. Debug and resolve production issues in systems with complex interdependencies and real operational takes. Collaborate with payment operations teams to onboard new payment methods and gateway providers. Ensure compliance with PCI‑DSS and other financial industry standards. Participate in on‑call rotation for production payment system support. Required Technical Skills 7+ years of professional C++ development experience in production environments. Modern C++ fluency and strong understanding of systems programming, including memory management, concurrency, and performance optimization. Ability to reason about undefined behavior and its practical consequences across platforms. Systematic debugging methodology. Toolchain understanding and cross‑compilation concerns. Proficiency with build systems – Bazel experience highly valued; experience with legacy codebases older than 10 years. Experience with or strong interest in payment processing or financial transaction systems. Deep knowledge of security best practices. Proficiency with AI‑assisted development tools (e.g., Claude, Codex) with mature judgment. Understanding of protocols and RESTful API design. Experience with Linux/Unix environments. Rust experience or genuine interest in learning it. gRPC experience or familiarity with service decomposition from monolithic architectures. Payment gateway integration experience (Chase Paymentech, Braintree, Adyen, or similar). PCI‑DSS compliance knowledge and implementation experience. Experience with platform migrations (e.g., Windows to Linux, MSVC to Clang). Bazel build system expertise. Performance profiling experience. Experience with shared memory, IPC frameworks, or low‑level concurrency primitives. Kafka or other event streaming platforms experience. OpenSSL/cryptographic libraries hands‑on experience. Familiarity with AI‑powered code review and static analysis tools. Awareness of security considerations when using AI tools with legacy or under‑documented systems. Behavioural Skills Approaches legacy systems with respect and curiosity. Takes time to understand existing systems before proposing improvements. Continuously improves code and systems incrementally while maintaining stability. Balances modernization efforts with the realities of production environments that require high reliability. Demonstrates a strong security‑first mindset, especially in systems handling sensitive transactions. Understands the critical nature of payment processing and the need for accuracy, resilience, and uptime. Navigates complex systems with care, ensuring minimal disruption while driving improvements. Shows enthusiasm for evolving legacy systems into modern, scalable solutions. Systems thinker who can reason across layers—from compiler optimization to network latency to business impact. Strategic modernizer who prioritizes incremental improvements and can balance technical debt decisions pragmatically. Pragmatic problem solver who works effectively within legacy system constraints while steadily driving improvements. Growth‑oriented engineer motivated to evolve from maintenance work into system design, service architecture, and broader ecosystem ownership. Collaborative communicator who explains reasoning clearly, asks thoughtful questions, and engages constructively with peers. Detail‑oriented professional who understands the operational and financial impact of transaction processing systems. Open‑minded professional capable of challenging ideas respectfully and adapting perspective based on new information. Benefits & Perks Health: Medical, vision, dental and mental health benefits for you and your family, with access to a health care concierge, and Flexible or Health Savings Accounts (FSA or HSA). Self‑care: Free concert tickets, generous paid time off including paid holidays, sick time, and personal days. Wealth: 401(k) program with company match, stock reimbursement program. Family: New parent programs including caregiver leave, plus fertility, adoption, foster, or surrogacy support.
