Paymentech Jobs (NOW HIRING)

Job Summary:

Location: Remote North Calorina, remote Miami, Remote Florida

Division: Ticketmaster, Payments

Line manager: VP Marketplace Engineering

Contract terms: Permanent, full time

THE TEAM

We're seeking an experienced C++ engineer to join our Platform Payments team, working on Ticketmaster's mission-critical payment processing systems. These systems process millions of transactions monthly across multiple payment methods and 20+ gateway providers, powering real-time payments for culture-defining live events at massive global scale.

THE JOB

You'll work across a mature C/C++ codebase spanning three decades - from pre-standard patterns in our core authorization gateway to C++17 in our Bazel monorepo. The immediate work is maintenance and strategic modernization of these systems, but this role is explicitly designed to grow: from legacy renovation into systems design, gRPC service architecture, and new technology adoption including Rust. If you're energized by the challenge of understanding why a system was built the way it was before deciding what it should become, this is the role.

This is not a maintenance job with a maintenance ceiling. You'll work on systems that power how fans pay for live events worldwide - at a scale where a misconfiguration can cause thousands of payment failures during a major onsale. The intellectual challenge is real: strategic modernization of systems spanning three decades of C++, with a clear trajectory into new technology.

There is tremendous green-field work ahead: decomposing legacy IPC into gRPC services, strengthening real-time fraud defenses during peak onsales, optimizing seamless global checkout, integrating new payment methods, and expanding embedded finance that shapes not just ticket purchases but the full in-venue experience. A strong engineer in this role will meaningfully shape the direction of these critical systems.

WHAT YOU WILL BE DOING

• 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

WHAT YOU NEED TO KNOW (or TECHNICAL SKILLS)

• 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

• Systems thinker who can reason across layers - from compiler optimization to cache behavior to network latency to business impact

• Strategic modernizer who understands incremental improvement over wholesale rewrite and can articulate when to pay down technical debt versus when to live with it

• Security-conscious developer who treats buffer safety, memory safety, and integer correctness as default concerns, not afterthoughts

• Pragmatic problem solver who can work within the constraints of legacy systems while steadily steering them forward

• Growth-oriented engineer who starts in maintenance but is motivated to grow into systems design, gRPC service architecture, and broader payments ecosystem work

• Collaborative communicator who explains reasoning clearly, asks good clarifying questions, and engages as a peer - can disagree constructively and change their mind when presented with new information

• Detail-oriented professional who understands the operational stakes of financial transaction processing

• Systems thinker able to reason across layers-from low-level performance (compiler optimization, cache behavior, network latency) to overall business impact

• Strategic modernizer who prioritizes incremental improvements and can balance technical debt decisions pragmatically

• Security-conscious developer who treats memory safety, buffer handling, and data integrity as foundational principles

• 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 articulates reasoning clearly, asks thoughtful questions, and engages constructively with peers

• Open-minded professional who can challenge ideas respectfully and adapt perspective based on new information

• Detail-oriented with a strong understanding of the operational and financial impact of transaction processing systems
