📋 Description

• 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 — this is the bridge from maintenance into systems design • 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

🎯 Requirements

• 7+ years of professional C++ development experience in production environments • Modern C++ fluency • 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 working with legacy codebases older than 10 years — ability to understand, respect, and incrementally modernize existing systems • 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 — uses AI as an accelerator that requires human verification, especially in codebases with undefined behavior where AI-generated code can appear correct and still be wrong • Understanding of HTTP/HTTPS 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

🏖️ Benefits

• 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) • Free concert tickets, generous paid time off including paid holidays, sick time, and personal days • 401(k) program with company match, stock reimbursement program • New parent programs including caregiver leave, plus fertility, adoption, foster, or surrogacy support • Career and skill development programs with School of Live, tuition reimbursement, and student loan repayment • Volunteer time off, crowdfunding match
