About The Position

Swiftly is seeking a Senior Software Engineer to join a cross-functional product team focused on enabling transit agency customers to operate and manage on-vehicle hardware systems and devices. This role involves working across a technology stack that connects cloud-native services with Swiftly’s core data engine to various embedded/IoT devices on public transit vehicles. The engineer will write software for edge devices, build communication layers between devices and the cloud, and develop backend services for configuration, control, and data processing. Swiftly values candidates with a growth mindset, learning aptitude, and strong motivation to deliver customer impact, encouraging applications even if not all requirements are met.

Requirements

5+ years of software engineering experience, with meaningful time spent working on embedded systems, IoT platforms, or edge computing
Proficiency with Linux including imaging, system administration, containerization, process management, networking, and security
Experience with communication protocols and paradigms of multiple varieties: serial interfaces (RS-232, J1708, CAN), network protocols (HTTP/REST, UDP v. TCP), and messaging patterns (MQTT, pub/sub, store-and-forward)
Familiarity with approaches to remote deployment and update mechanisms (eg. OTA updates, A/B partitioning, configuration management, edge container orchestration)
Interest in being hands on with code and devices, whether your comfort level is plugging in an ethernet cable or crimping your own
A testing and quality mindset, with strong opinions on system validation, automated testing, observability, and monitoring
Comfort applying modern AI tools to accelerate development and improve quality
Proficiency with languages and technologies in our stack: Python, Java, Javascript/Typescript, MQTT, SQL databases
Experience with cloud-native architectures and services (AWS preferred)
Strong product mindset — you use technology pragmatically to solve meaningful customer problems
Continuous learner who embraces emerging technologies and helps others grow
Collaborative team player who contributes wherever needed to support team goals
Open to feedback (a core Swiftly value!), humble in technical debate, and committed to blameless learning and improvement
