Role description
As a Senior Software Engineer, you will be a key driver of our distributed backend ecosystem. You will be responsible for building and maintaining the services that connect our cloud infrastructure to our fleet of Ubuntu-based field devices. Working closely with our Staff Engineer and CTO, you will help turn complex requirements into reliable, production-ready code. This role is ideal for a seasoned engineer who enjoys the intersection of cloud-native microservices and Linux-based system automation.
Technical Requirements
1. Backend Engineering & Go
- 6–8+ Years of Backend Experience: A proven track record of shipping and maintaining production services.
- Go (Golang) Proficiency: While Go doesn't need to be your current primary language, you have direct experience writing and deploying Go in a professional environment and can contribute to our codebase immediately.
- Microservices & API Design: Experience implementing decoupled microservice architectures and developing RESTful APIs (both internal and public-facing).
- Modern Authorization: Familiarity with relationship-based access control (ReBAC). Experience with OpenFGA or similar Zanzibar-style logic is a plus.
2. Cloud & Infrastructure
- Cloud Infrastructure (AWS): Familiarity with managing and deploying applications within a cloud environment, preferably AWS.
- Data Persistence & Caching: Solid proficiency in SQL (e.g. PostgreSQL) and experience using caching systems (e.g. Redis) to optimize application performance.
- CI/CD & Automation: Experience using automated deployment pipelines and a desire to build portable, efficient workflows.
- Containerization: Practical experience with Docker for local development and containerized deployments.
3. Linux & Edge Systems
- Linux (Ubuntu) Proficiency: Strong command of the Linux environment. You are comfortable writing Bash scripts and managing software within an Ubuntu-based system.
- Custom Orchestration: Comfort working with custom deployment mechanisms for pushing software updates and Docker images to remote hardware in the field.
- Systems Mindset: You understand the challenges of remote device management, such as handling intermittent connectivity and resource constraints.
Key Responsibilities
- Core Development: Design and implement backend features in Go, ensuring they are performant, secure, and maintainable.
- Technical Collaboration: Work as a primary partner to the Staff Engineer to execute architectural plans and maintain high engineering standards across the stack.
- Public API Maintenance: Help manage and evolve our Public API, ensuring a high-quality experience for external developers and internal systems alike.
- System Reliability: Maintain and optimize our SQL databases and caching layers to ensure the system scales as our device fleet grows.
- Edge Orchestration: Manage the lifecycle of software bundles (Go binaries and scripts) running on our field devices via our custom deployment pipelines.
Nice-to-Haves (Training Provided)
We prioritize core backend engineering and systems thinking. If you don't have experience in the following, we are happy to provide the training:
- Industrial Protocols: Interfacing with BACnet and Modbus hardware.
- Wireless Connectivity: Understanding LoRaWAN or other long-range communication protocols.
- AI & Future Tech: Helping build our RAG-based AI agent and working with vector-based search.
- Python: Familiarity for specific data-handling tasks or AI-adjacent integrations.
The Senior Profile
You are a "builder" who values architectural clean lines and operational stability. You understand that a distributed system is only as strong as its weakest link—whether that’s a misconfigured AWS VPC or a permissions error in a Bash script on a field device. You enjoy the autonomy of owning large features and the challenge of bridging the gap between high-level cloud logic and low-level system execution.
