Sr. Software Engineer (SafePointe)

Position Overview

SoundThinking is seeking a Senior Software Engineer to accelerate development of SafePointe®, our AI-based concealed weapons detection system designed for high-throughput, free-flow screening. SafePointe combines passive magnetic sensing with an advanced 3D camera and NVIDIA-powered edge processing to detect metallic firearms while minimizing operational friction.

This role is for someone who is an expert in Python, highly capable of deploying and operating cloud-based products, and thrives in rapid prototyping—turning ambiguous problems into shippable, reliable services.

Essential Responsibilities/Duties

Edge-to-Cloud Integration

• Build robust interfaces between edge devices and cloud infrastructure (device enrollment, secure connectivity, configuration, health monitoring, version management)
• Partner with embedded/sensor and ML teams to ensure cloud services support model rollout, diagnostics, and quality feedback loops
  
  

Sensor Systems Collaboration (Interface to Sensor Engineering)

• Define and own the sensor data contract from edge to cloud: telemetry schemas, calibration/firmware metadata, diagnostics, and traceability identifiers.
• Partner with Sensor Engineering to translate sensor KPIs (noise floor, dynamic range, saturation/clipping, drift, CMRR/gradiometry) into measurable software health checks, alerts, and acceptance tests.
• Build and maintain tooling for time-synchronized captures (sensor camera) and dataset packaging to support debugging, labeling, and ML feedback loops.
• Enable remote diagnostics and field triage by exposing sensor health signals (timing/synchronization, data integrity, self-test status) through APIs, dashboards, and logs.
• Support manufacturing and deployment workflows by integrating calibration results and production test outputs into cloud services and operational processes.
  
  

Rapid Prototyping & Iteration

• Quickly prototype new features end-to-end (API → service → UI/dashboard if needed), validate with stakeholders, then harden for production
• Develop internal tooling to speed debugging, data analysis, and system verification (Python utilities, automated tests, regression harnesses)
  
  

Cloud Product Engineering (Python-first)

• Design and build cloud services and APIs that support SafePointe workflows (alerts, event processing, configuration, monitoring, reporting) using Python
• Own production deployments: CI/CD, infrastructure-as-code, environments, release processes, and operational readiness (observability, on-call hygiene, incident response)
• Implement secure, scalable data pipelines and storage patterns for device/telemetry/event data; ensure reliability and performance at scale
  
  

Engineering Excellence

• Write high-quality, well-tested code; lead code reviews; drive pragmatic architecture decisions and technical standards
• Produce clear technical documentation (APIs, runbooks, deployment and validation procedures)
  
  

Minimum Qualifications

• 6 years of professional software engineering experience, including ownership of production cloud services
• Expert-level Python (APIs, services, async/concurrency, testing, performance profiling)
• Working proficiency in C on Linux (ability to read, debug, and make small-to-medium contributions in a mixed C /Python edge codebase)
• Familiarity with gdb, profiling/perf basics, and debugging concurrency/memory issues on edge systems
• Strong experience deploying cloud-based products on AWS/Azure/GCP (or equivalent), including:
• Containers (Docker), CI/CD, and environment management
• Observability (metrics/logs/tracing), reliability practices, incident response
• Experience designing RESTful APIs and service integrations (FastAPI/Flask/Django acceptable)
• Strong database fundamentals (SQL; Postgres preferred) and production data modeling
• Comfort collaborating with embedded/sensor engineers and reasoning about sensor/DAQ constraints (sampling rate, latency, clock sync, data integrity) to design robust software interfaces.
• Experience working with time-series telemetry and building diagnostic/analysis tools (e.g., Python/numpy/pandas) to support root-cause analysis.
• Excellent debugging and problem-solving skills; ability to move from prototype to durable production systems
• Experience with event-driven systems / streaming (e.g., queues, pub-sub, Kafka/Kinesis, Celery)
• Infrastructure-as-code (Terraform/CDK), Kubernetes, service security (authN/authZ), and secrets management
• Experience building dashboards/ops consoles for configuration and diagnostics
• Familiarity with edge/IoT architectures and secure device communications
• Experience with JavaScript/TypeScript and modern web frameworks (React/Next.js) for building internal tools or dashboards
• Prior work in physical security, safety, or other high-reliability domains
  

Technical Stack (Representative)

• Backend/Services: Python, FastAPI/Flask/Django, REST APIs
• Cloud/DevOps: Docker, CI/CD, IaC, observability tooling
• Data: Postgres (plus fit-for-purpose caches/queues/object storage)
• Edge/On-device: C and Python on Linux
• Workflow: Git, code review, structured documentation
• Travel 15%
• Location: Mt. Dora Office
