Position Description:

We’re looking for a Senior Software Engineer (III) with strong Python expertise and a track record building software that interacts with hardware, Linux-based platforms, and networked systems. This role will contribute across device-side applications, services, and supporting tools used to develop, deploy, and operate connected retail and restaurant technology products.

You’ll work closely with cross-functional partners (firmware, hardware, cloud, QA, and product) to deliver robust, diagnosable, and maintainable systems. The ideal candidate is comfortable moving between system-level debugging (Linux, networking, logs) and product-facing experiences, and has an interest in building intuitive front-end tools for configuration, monitoring, and diagnostics.

Position Location: New Hartford, New York or Remote, United States

Reports To: Sr. Director of Engineering

What We’re Looking For:

· 6+ years of professional software development experience, including substantial Python development.

· Strong experience developing on Linux (processes, services/daemons, systems, logging, packaging).

· Experience building networked systems: TCP/IP fundamentals, sockets, HTTP/REST, secure communications (TLS), and debugging network issues.

· Experience designing and shipping software for hardware-adjacent or device-integrated environments (edge computing, peripherals, gateways, appliances, or similar).

· Front-end UI development experience using modern frameworks such as React, and Angular and/or meta-frameworks.

· Solid software engineering fundamentals: API design, test strategy, code reviews, CI/CD, and maintainable architecture.

· Strong collaboration and communication skills in cross-functional environments.

· Demonstrated experience in and comfort with all phases of the product development lifecycle including design, implementation, unit testing, debug, verification, validation, and transfer to manufacturing.

Additional skills:

· IoT/edge experience: device onboarding/provisioning, fleet management concepts, secure update flows, telemetry, and observability.

· Familiarity with common IoT protocols and patterns (e.g., MQTT, WebSockets), and message-driven architectures.

· Background in DSP and audio applications (audio pipelines, latency/echo/noise considerations, streaming/codec basics).

· Experience with real-time or performance-sensitive systems and profiling on Linux.

· Exposure to hardware communication interfaces (UART, I2C, SPI, USB) and/or integration with embedded firmware teams.

Unleash your potential: What you will be doing and owning:

· Design, implement, and maintain Python-based services and tooling that support connected retail/restaurant technology products.

· Build and support software running on Linux-based hardware platforms (edge devices /appliances), including service lifecycle management, logging, and resilience.

· Develop and integrate network communication layers (REST APIs, eventing, secure connectivity) for device-to-device and device-to-service interactions.

· Create internal and/or customer-facing web UIs for configuration, monitoring, diagnostics, and operational workflows using standard frameworks (e.g., React/Next.js, Vue, Angular).

· Partner with firmware and hardware teams to define interfaces, test strategies, and diagnostic hooks that enable rapid troubleshooting and stable releases.

· Improve engineering velocity by enhancing developer tools, test harnesses, CI pipelines, and automated verification where appropriate.

· Establish strong observability patterns: logs, metrics, traces, crash capture, and actionable field diagnostics.

· Participate in architectural reviews, code reviews, and technical mentorship of junior engineers.
