Sr. Software Engineer (Fremont, CA)

About the role

SoundThinking is re-architecting the ShotSpotter acoustic location engine into cloud-native microservices, enhancing location algorithms with 3D urban models, and integrating geospatial data sources. You will work closely with a ShotSpotter cofounder to develop next-generation acoustic location services.

Responsibilities

• Decompose and re-architect the monolithic LabVIEW-based location engine into AWS microservices (Lambda, EKS/Kubernetes, RabbitMQ, etc.)
• Design event-driven pipelines for real-time acoustic data ingestion, multilateration computation, and location refinement
• Collaborate with the cofounder to implement enhanced location algorithms incorporating 3D urban models to account for sound reflection, diffraction, multipath, and shadowing
• Integrate geospatial data sources (LiDAR, GIS, 3D city models) into the location computation pipeline
• Build simulation and back-testing frameworks to validate accuracy improvements against historical incident data
• Translate legacy LabVIEW signal processing and mathematical logic into maintainable, well-tested, modern codebases
• Define service boundaries, REST/gRPC APIs, CI/CD pipelines, and infrastructure-as-code
• Establish observability and monitoring for mission-critical services

Requirements

• 8+ years of software design and development experience in backend/distributed systems
• Advanced proficiency in Python and at least one systems-level language (C++, Rust, or Go)
• Strong AWS experience — you've designed and shipped microservice architectures using core services
• Experience with PostgreSQL, NoSQL databases, and message brokers (RabbitMQ, SQS/SNS)
• Experience decomposing monolithic systems into microservices
• Experience with complex distributed, event-driven architectures
• Strong foundation in applied mathematics, physics, or signal processing — comfortable with multilateration, TDOA, optimization algorithms, and numerical methods
• Experience with Kubernetes, Linux, Git, CI/CD tools, infrastructure-as-code
• Excellent communication and collaboration skills

Qualifications

• Bachelor's degree in computer science, engineering, physics, or related field (advanced degree preferred)

Skills

• Nice-to-have: Experience with acoustic modeling, computational acoustics, or wave propagation simulation
• Familiarity with 3D geometry processing, ray tracing, or computational geometry
• Background with LabVIEW or migrating from LabVIEW/MATLAB to production systems
• Experience with IoT device management, GIS platforms, LiDAR, or 3D city model formats
• Experience with machine learning pipelines
• Experience in defense, public safety, or mission-critical domains

Benefits

This is life-safety software — your code will directly impact how fast and accurately gunfire is located in real cities.

Pay

The typical base salary range for this role is $140,000 - $165,000 annually. This range reflects base salary only and does not include bonus, sales incentives, equity, or benefits, where applicable.

Schedule

The position offers a hybrid workplace with a minimum of 3 days per week required to be onsite, depending on the office location. The specific days for in-office are dependent on the office location.
