Senior Software Engineer, Backend

Role Overview

Archiboost AI is building an AI co-pilot for the AEC industry — automating code compliance, structuring firm knowledge, and performing real-time QA/QC across complex building projects. As a Senior Backend Engineer, you'll build the core infrastructure, data systems, and AI pipelines powering this vision. This isn't a typical backend role — you'll work on retrieval over large-scale architectural datasets, AI reasoning across drawings and codes, and distributed systems supporting LLM-powered workflows. You'll collaborate closely with product, ML, and design to turn complex architectural workflows into scalable systems.

What You'll Work On

• Retrieval systems over large, unstructured architectural and regulatory datasets
• AI pipelines that reason across drawings, codes, and specifications
• Multi-step agents performing QA/QC across building projects
• Distributed systems managing compute-heavy (CPU/GPU) workloads
• Evaluation frameworks for domain-specific AI performance
• Real-time collaboration between humans and AI on design artifacts

Responsibilities

• Build and scale backend systems for AI-driven workflows
• Design APIs orchestrating LLMs, retrieval, and reasoning systems
• Develop pipelines for processing drawings, documents, and BIM data
• Architect distributed systems for large-scale, multi-region datasets
• Optimize performance, latency, and cost of AI workloads
• Productionize LLM/agent systems and improve reliability and observability
• Contribute to core architecture, infrastructure, and engineering standards

Required Qualifications

• 5+ years backend engineering experience
• Strong skills in Python, Go, or TypeScript
• Experience with distributed systems and scalable APIs
• Solid CS fundamentals (systems, data structures, concurrency)

Preferred Qualifications

• Experience with LLMs, RAG, or vector databases
• Large-scale data pipelines or document systems
• Cloud infrastructure (AWS/GCP)
• GPU workload optimization
• Startup experience

Why Archiboost AI

• Redefine how buildings are designed, validated, and delivered
• Build an AI co-pilot for a massive, underserved industry
• Work on real-world systems combining document understanding, retrieval, and reasoning
• Partner with leading architecture firms and top-tier investors
• Join early, ship fast, and own meaningful technical decisions
