Software Engineer, Full Stack; Backend Focus - Intermediate

About Hedral

Hedral is redefining building design through automated, multi-disciplinary engineering.

We develop and operate a proprietary platform that accelerates design schedules, enabling us to deliver the output of traditional AEC firms ten times our size. We are fully licensed to stamp these designs as Engineer of Record and take responsibility for highly-consequential projects, from mission-critical federal facilities to complex commercial infrastructure.

We are scaling quickly with backing from leading venture capital including Khosla Ventures, Valor Equity Partners, and Tishman Speyer.

As a Full Stack Engineer (Backend Focus), you will architect and maintain the critical systems that bridge high-fidelity building engineering with scalable software. You will have end-to-end ownership of complex data models and high-performance backend services, ensuring technical robustness as we scale. We are seeking a systems-minded builder who excels in a rapid-iteration environment and is comfortable moving across the stack to deliver the infrastructure that powers our automated design platform.

Austin, TX or New York, NY - Primary preference for Austin or NYC; remote-eligible for exceptional candidates with a proven track record.

• Build For Scale: Design and maintain a robust backend in C# (.NET) and Python (FastAPI) capable of handling large-scale, interconnected engineering datasets.

• Performance Engineering: Implement a high-performance ECS (Entity Component System) and manage complex data flows to support real-time engineering solvers.

• Bridge The Stack: Develop and optimize APIs (Graph
  
  QL, gRPC, or REST) that feed a real-time, browser-based React frontend.

• Full-Spectrum Contribution: Maintain a "no-silos" mentality, contributing to different areas of the codebase—from infrastructure to frontend—leveraging AI-assisted workflows to accelerate output.

• System Evolution: Design database schemas (Postgre
  
  SQL) and services with an eye toward future high-performance migrations (e.g., Rust/C++).

• Education: BS in Computer Science, Engineering, or a related technical discipline.

• Experience: 3+ years of professional software engineering experience.

• Modern Workflow: Proficiency with AI-powered IDEs (Cursor, Copilot, etc.) and a commitment to using AI to multiply individual impact.

• Full Stack Proficiency: Competent in React and Type Script to ensure seamless integration between backend logic and UI.

• Backend Mastery: Deep proficiency in C# / .NET or Python (FastAPI), with a strong interest or experience in systems-level languages like Rust or C++. You should have a solid grasp of memory management, asynchronous programming, and architecting for low-latency performance.

• Data Architecture: Strong experience with relational databases (
  PostgreSQL
  ) and API design.

• Cloud & Infra: Proficiency with AWS/Azure/GCP, Docker, and CI/CD (Git Hub Actions).

• Startup DNA: Experience in a fast-paced, high-growth, or agile startup environment.

• Domain Expertise: Familiarity with CAD, BIM, 3D web graphics (Three.js), or structural simulation.

• Real-Time Systems:
  
  Experience with real-time collaboration tools (Signal
  
  R, Y.js, or similar).

• Technical Foundations: Solid understanding of linear algebra, geometry, or physics-based computing.

• Ownership & Intensity: Maintain high autonomy and a shared sense of urgency to redefine the AEC industry.

• Compound Leverage: Iterate and ship quickly. The best engineers here automate their own workflows and focus on higher-order problems.

• Adaptive Learning: Step out of your comfort zones. Whether it's learning a new language or mastering a new AI tool, we expect everyone to continuously expand their technical range and evolve with the tools they use.

• Data-Driven Decisions: Our core advantage is that our system learns from real, stamped engineering work. Every project feeds back into the model.

• Competitive Compensation and Benefits: We take care of our people so they can perform at their highest level.

• Environment for Growth: Our offices are intentionally located near the most important projects across the country. Site walks and frequent AMAs with guest speakers keep us up to date with the evolving state of AEC. You never know who you’ll run into at the coffee machine.

• High-Stakes Technical Ownership: Direct responsibility for the systems that power mission-critical federal and commercial infrastructure.

• Cosmopolitan, Tight-Knit Team: We hail from all over the world, and our office decor, snack cart, and Slack channels reflect that. When someone travels, the group chat fills with photos of vernacular MEP systems, scaffolding details, and architectural marvels.
