Key Responsibilities

• Independently drive project delivery within defined architecture, demonstrating autonomy and accountability in all stages from conceptualization to deployment.
• Build and optimize high-volume ingest pipelines in Go, including concurrency design, buffering, back-pressure, and retry semantics.
• Implement and maintain device polling and collection across IoT and OT telemetry protocols, and the write path into time-series storage.
• Profile and tune for throughput, latency, and memory footprint, especially in edge and constrained-runtime deployments.
• Craft client code that is not just efficient but also performant, testable, scalable, secure, and of the highest quality.
• Actively participate in accurate planning and estimation efforts, utilizing project methods and tools.
• Contribute to code reviews and technical documentation, and partner with the technical lead on resiliency and failure-isolation design.
• Take part in knowledge transfer from the outgoing delivery team and help ramp up engineers joining behind you.
• Engage in agile software development, including daily stand-ups, sprint planning, team retrospectives, and other governance activities.
• Actively participate in the Engineering Practice community, mentoring others through Communities of Practice (CoPs) or on project teams and supporting the growth of technical capabilities.

Minimum Qualifications:

• A minimum of 5+ years of professional software engineering experience, with demonstrable depth in Go.
• Strong concurrency and performance engineering skills: goroutine and channel design, profiling, memory and allocation tuning, benchmarking.
• Solid network protocol fundamentals and hands-on protocol-level work, including debugging with packet captures.
• Experience building high-volume ingest or streaming pipelines in production.
• Working experience with time-series storage such as InfluxDB or equivalent, including write optimization and schema and tag design.
• Experience in creating and implementing well-tested, scalable, and performant enterprise-level systems.
• Experience in Agile software development methodologies.
• Good understanding of SOLID principles and familiarity with OWASP.
• Proficiency in the English language.
• Must be authorized to work in the United States.

Additional Experience Desired:

• Exposure to IoT or OT telemetry protocols such as SNMP, gNMI or other streaming telemetry, NETCONF, syslog, and MQTT. This is preferred, and weighted below Go depth and network fundamentals.
• Python for tooling and data work.
• Containers and orchestration using Docker and Kubernetes.
• Observability instrumentation: metrics, tracing, and structured logging.
• Prior data center, DCIM, industrial, or critical-infrastructure monitoring background.
• Experience with CI/CD pipelines and cloud native application patterns.
