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 Senior Systems Engineer will design, develop, and support communications and encryption devices, providing technical expertise in cryptographic technologies and deployment strategies. Responsibilities include advising on cryptographic equipment deployment, analyzing emerging threats, conducting technical analysis of cryptographic products for acquisition decisions, liaising with vendors on device lifecycle, and supporting leadership with briefings and fielding decisions. The role requires 5–15 years of cybersecurity, systems engineering, or network security experience, along with strong analytical, problem-solving, and written communication skills. A bachelor's degree in Systems Engineering, Computer Science, or related field is required.

Design and own network security across Saronic's enterprise, on-premises, cloud, and maritime vessel communications infrastructure. Responsibilities include managing firewalls, segmentation, VPN/ZTNA, and wireless systems (Palo Alto, Cisco, Aruba); securing AWS VPC architecture in commercial and GovCloud; architecting secure vessel communications over cellular, RF, SATCOM, and mesh links with cryptographic key management; and building network observability and automation at scale. Requires 5+ years of hands-on enterprise network security experience, production firewall and VPN operations, L3-L7 networking fundamentals, and the ability to obtain a U.S. security clearance.

Senior Software Engineer supporting next-generation tools and systems development at a defense/intelligence contractor. Responsibilities include designing and implementing AI-assisted web-based applications that integrate with custom embedded systems, writing requirements and test documentation, executing tests, and interfacing with customers on requirements and design reviews. Requires 6+ years of software engineering experience, proficiency in Python, C# or Rust, JavaScript/TypeScript, HTML/CSS, Linux systems expertise, web-based UI development skills, and network software engineering knowledge (TLS/HTTPS). Must hold or be able to obtain a DoD SECRET clearance.

SAIC seeks a Cloud DevOps Engineer to design, build, and operate mission-critical cloud infrastructure on AWS and Kubernetes/OpenShift platforms in support of Naval Operational Architecture. The role combines infrastructure-as-code (CloudFormation, YAML), container orchestration, Linux/Windows server administration, networking, scripting (Bash, Python, PowerShell), and cybersecurity hardening (STIGs, ACAS). You will work across cyber, networking, and development teams to deliver resilient, secure, and highly available cloud environments while maintaining compliance and system uptime.

Design, build, and operate cloud-native platform features and services with hands-on engineering focused on Kubernetes, distributed systems, and infrastructure automation. Deliver well-defined work iteratively from implementation through production, contributing to reliability, scalability, and operability through testing, instrumentation, and on-call participation. Collaborate with senior engineers on platform standards while mentoring junior team members. Requires 5+ years of software development experience (or equivalent), production experience with Kubernetes, exposure to at least one major hyperscaler (AWS, Azure, GCP), and proficiency in Go or another systems language.

Lead a mobile engineering team building Flutter and native iOS/Android applications for an Automated Insulin Delivery (AID) medical device ecosystem. Manage developers proficient in Kotlin, Swift, and Objective-C while collaborating with systems architects, quality teams, and cross-functional stakeholders to deliver robust, secure mobile apps in a regulated healthcare environment. Provide technical direction, conduct design reviews, coach team members on software development principles, and drive product quality through agile/scrum practices.
