Senior Software Engineer (backend) Full Time Columbus HQ / Remote

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)

• 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.
