About the RoleBoon AI is building the agentic operating system for construction preconstruction - the layer that reads blueprints, specs, and bid documents, and does the estimator's work with them. Our platform spans a Rails product monolith, Python computer-vision services (DINOv3/SAM-class vision models reading drawings), an LLM agent runtime orchestrating multi-step construction workflows, and model/eval infrastructure that keeps accuracy honest. We're live with GCs and subs across the country, shipping daily, and scaling from thousands to hundreds of thousands of drawings per month.
As a Senior Software Engineer, you'll own meaningful features and services across this platform, solve challenging technical problems, and help build a system that scales with our customers.
In this role, you will:- Own features and services end to end across the Rails product app, Python ML/CV services, agent SDK layer, and data platform - balancing customer requirements, maintainability, and shipping speed
- Improve the scalability, reliability, and cost efficiency of our computer vision/LLM/VLM inference pipelines as we scale blueprint throughput
- Build and improve our model infrastructure, including vision model integration, LLM orchestration, agent workflows, MLflow registry, and eval harnesses
- Contribute to architectural decisions, write clear design docs, and raise the engineering bar through thoughtful code review
- Share knowledge and mentor teammates as the engineering team grows
- Partner with product and engineering teammates to scope work, evaluate build-vs.-buy decisions, and turn customer needs into reliable software
- Write and ship production code regularly, troubleshoot issues, and participate in incident response
You're a Great Fit If:- You've shipped production systems that handle messy real-world input - documents, PDFs, images, OCR, or user-generated data
- You have sound engineering judgment about when to add complexity, when to keep things simple, and when to use proven open-source or paid solutions
- You've built or operated computer vision or LLM/agent systems in production, or have strong adjacent experience and want to work deeply in this space
- You care about testing and evals as practical tools for improving accuracy and reliability
- You move fast while keeping the foundations strong, and can recognize when a part of the system needs investment
- You thrive in flat, direct, high-velocity teams where technical decisions are grounded in code, data, and customer needs
- Bonus: construction, AEC, or other vertical-SaaS experience; or experience helping a product scale at a growing startup
- Culturally, you embody working as "one team" and strive to "get things done," taking ownership and helping teammates move work forward
Requirements for the Role:- 3+ years of experience building production software, with a track record of delivering in fast-paced environments
- Strong experience in at least one of: Rails or Python applications, production computer vision pipelines, LLM/agent systems, or data-intensive B2B SaaS
- Hands-on experience with cloud infrastructure (AWS and/or GCP), PostgreSQL, background job or messaging systems (such as Sidekiq or RabbitMQ), and modern deployment practices
- Experience owning features or services from technical design through deployment and ongoing operation
- Strong coding, debugging, and code review skills, with recent experience shipping production code
- Familiarity with SRE and DevOps practices, such as CI/CD, Kubernetes, or Helm, and the ability to collaborate with Boon's dedicated SRE teammates
CompensationAt Boon, we want to attract and retain the best employees and compensate them in a way that appropriately and fairly values their individual contribution to the company. With that in mind, we carefully consider a number of factors to determine the appropriate starting pay for an employee, including their primary work location and an assessment of a candidate's skills and experience, as well as market demands and internal parity. This estimate can vary based on the above mentioned factors, so the actual starting annual base salary may be above or below this range. A Boon employee may be eligible for additional forms of compensation, depending on their role, including sales incentives, discretionary bonuses, and/or equity in the company.
