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.

Senior Systems Software Engineer role at Saronic Technologies focused on designing, developing, and optimizing software systems for autonomous surface vessels. Responsibilities include implementing autonomous navigation and control algorithms, integrating software with hardware systems, optimizing network communications for low-bandwidth/high-latency environments, and conducting software testing and validation. The role requires 3+ years (Senior) or 8+ years (Staff) of software engineering experience, preferably in autonomous systems or robotics, with proficiency in C/C++ or Rust, embedded Linux systems, and knowledge of low-level protocols and networking principles.

Design, develop, and maintain software systems for autonomous surface vessels using NixOS, embedded Linux, and low-level protocols. Implement control algorithms and sensor fusion, optimize network communications for bandwidth-constrained maritime environments, and collaborate with hardware engineers to integrate software with vessel systems. Requires 3+ years (Senior) or 8+ years (Staff) of software engineering experience, proficiency in C/C++ or Rust, strong embedded systems knowledge, and familiarity with protocols like CAN and TCP/IP.

Design, develop, and maintain software systems for autonomous surface vessels using NixOS, embedded Linux, and low-level protocols. Implement algorithms for autonomous navigation, controls, and sensor fusion while optimizing network communications for maritime environments with low bandwidth and high latency. Collaborate with hardware engineers to integrate software with vessel systems and conduct rigorous testing and validation in real-world conditions. Candidates must have 3+ years of software engineering experience (senior level) or 8+ years including architecture and platform leadership (staff level), with proficiency in C/C++ or Rust and strong understanding of embedded systems, networking, and control systems.
