Job Description: Our client is seeking a Product Software Engineer to help design and build the foundational architecture of a next-generation physical security platform. This is a 100% greenfield, backend-focused product engineering role where you will build services, integrations, identity and authorization capabilities, and real-time messaging infrastructure from the ground up. The ideal candidate is a builder who thrives in a small team, enjoys solving ambiguous technical problems, and has hands-on experience developing production backend software, cloud-based pub/sub or IoT systems, and secure authentication and authorization solutions.
Day-to-Day Responsibilities:
- Design and build backend APIs and microservices supporting user and device identity, token validation, and authorization.
- Develop enterprise authorization capabilities using RBAC, ABAC, and related access-control models.
- Architect and secure serverless publish/subscribe messaging infrastructure across modern cloud environments.
- Build IoT and edge-ingestion capabilities using MQTT and secure machine-to-machine communication.
- Design data pipelines that ingest streaming telemetry and reliably persist data within cloud-based data stores.
- Build integrations with access-control, video, alarm, sensor, and other physical security platforms using vendor APIs, SDKs, and event streams.
- Implement authentication and authorization using technologies such as OAuth 2.0, OpenID Connect, JWT, and SAML.
- Design secure logging, auditing, monitoring, and threat-detection capabilities for edge and cloud access requests.
- Build proof-of-concepts and prototypes to evaluate new technologies and architectural approaches.
- Help design scalable systems from the ground up rather than maintaining an established architecture.
- Evaluate technical approaches and clearly communicate tradeoffs and recommendations.
- Collaborate closely with Product, Security, Operations, and Engineering stakeholders.
- Take ownership of technical decisions and remain accountable for outcomes.
- Translate complex technical concepts for both technical and nontechnical stakeholders.
- Experiment with new technologies and help determine how they can be incorporated into the evolving product platform.
Minimum Requirements:
- 3–5+ years of professional product software engineering experience with a strong focus on backend development.
- Professional experience developing production software in Go, C#/.NET, and/or Python, with Go and .NET particularly valuable.
- Experience building backend APIs, microservices, or distributed systems in a commercial product environment.
- Hands-on experience with cloud infrastructure across AWS, Azure, and/or GCP, ideally with strong experience in at least two major cloud platforms.
- Experience with MQTT, publish/subscribe messaging patterns, broker integrations, IoT, or comparable distributed messaging technologies.
- Experience building serverless messaging solutions using technologies such as AWS IoT Core, SNS, SQS; Azure IoT Hub, Service Bus, Event Hubs; or Google Cloud Pub/Sub.
- Hands-on authentication and authorization experience.
- Strong understanding of OAuth 2.0, OpenID Connect, JWT, and related identity protocols.
- Experience with role-based and/or attribute-based access control.
- Experience with containers and modern cloud-native development.
- Understanding of PKI, TLS, X.509 certificates, and secure software-development practices.
- Experience building proof-of-concepts, prototypes, or new systems from the ground up.
- Experience taking a product, feature, or technical capability from initial concept through production launch.
- Bachelor's degree in Computer Science, Engineering, Information Technology, or a related technical field.
- Strong communication skills with the ability to explain technical concepts to both technical and nontechnical stakeholders.
- Builder mentality with a curious, hands-on approach to solving technical problems.
- Ability to operate effectively in an ambiguous greenfield environment and independently make technical decisions.
Preferred Qualifications:
- Physical security technology experience.
- IoT product development experience.
- Identity and access management software experience.
- Experience integrating access-control, video, alarm, or sensor platforms.
- Policy-as-code experience.
- Experience modernizing legacy infrastructure into managed, serverless ingestion or messaging services.
- Open-source contributions involving identity, IoT, distributed messaging, or streaming data.
- Experience using AI-assisted development tools.
- Experience building high-volume streaming or telemetry platforms.
- Experience working on small, highly collaborative product engineering teams.
