Senior back-end engineer to own and re-architect the payment-terminal platform powering restaurant kiosks, currently spanning 40+ integrations across card-present terminals, processors, and cash automation. You will design a modular, pluggable SDK enabling internal and external developers to build integrations against a stable contract, implement new integrations from wire-level protocols (TLV, BMP, APDU, BCD/LLVAR) up through high-level APIs, and establish platform-wide patterns for payment correctness (idempotency, transaction recovery, reconciliation). Role requires 6+ years back-end engineering with strong Java, Spring, OOP, and distributed-systems design; hands-on work with serial (RS-232/USB-serial via jssc) and USB (usb4java) transports, REST/SOAP/webhook integrations, and PCI-DSS compliance patterns.

The Data Architect is a hands-on technical leader responsible for designing and modernizing enterprise data architecture across on-premises and cloud platforms. The role defines scalable data models, integration patterns, and architectural standards for the Data Lake, Data Warehouse, ODS, and cloud platforms while ensuring security, resilience, and high performance. Working closely with engineering, analytics, and business teams, the architect provides technical guidance on modern data systems, governance frameworks, and ETL/ELT pipelines. The position combines strategic vision with practical experience optimizing structured, semi-structured, and unstructured workloads across SQL, NoSQL, and cloud-native systems.
Lead the architectural design of server-side, backend, and cloud platform capabilities supporting Dexcom's continuous glucose monitoring products. Collaborate across product, cybersecurity, firmware, data, and mobile teams to translate business and regulatory requirements into secure, scalable, and maintainable platform solutions. Establish architectural direction for distributed services, APIs, data pipelines, event-driven systems, and shared platform capabilities. Guide technology exploration, system integration, performance testing, and serve as an authority for platform architecture principles and modern backend development practices across the organization.
Design, develop, and sustain Windows desktop control software for complex electro-mechanical semiconductor test handlers using C++ and C#. Responsibilities span full lifecycle development—architecture, integration, deployment, and customer support—with focus on system uptime, safety, and reliability. Own hardware integration (motion controllers, machine vision, robotics, sensors, barcode readers), troubleshoot field issues, and drive system architecture across product variants. Mentor engineers and collaborate cross-functionally with manufacturing, field service, and customer teams.
Design, develop, and deploy end-to-end generative AI solutions including GenAI agents, LLMs, and applications to solve complex business challenges. Build data pipelines, design APIs for AI accessibility, and collaborate with cross-functional teams (developers, data scientists, business) to implement enterprise GenAI solutions. Requires 4+ years of full-stack application development (Java, Python, JavaScript) and 3+ years with data structures, algorithms, and data stores. Stay current with AI research and communicate technical concepts to non-technical stakeholders.
