Senior Full-Stack Software Developer

About ApexOS360
ApexOS360 is building an enterprise-grade operating platform for construction companies — project management, financials, field operations, document control, and real-time reporting in one system. Think Procore-level capability, built by people with 27+ years actually running construction projects across Texas and Colorado.

The Role
Own the entire product development process from day one. Architect, design, code, test, and deploy a production-grade SaaS platform on an aggressive timeline. You'll work directly with leadership, have full autonomy on technical decisions, and full accountability for results. This is a ground-floor opportunity to be the technical backbone of a product built to scale.

What You'll Do
- Own the full development lifecycle: architecture, design, development, testing, deployment, and iteration
- Design and build multi-tenant SaaS architecture with isolated data across multiple organizations
- Build modular platform structure (project management, financials, document control, field ops, reporting) that scales independently
- Develop data-rich front-end interfaces (React, Vue, or equivalent) including dashboards, Gantt charts, cost code views, and real-time collaboration tools
- Build robust back-end systems (Node.js, Python, or similar) with RESTful/GraphQL APIs and automated business logic workflows
- Design relational database schemas (PostgreSQL/MySQL) for complex construction data: projects, budgets, cost codes, change orders, contracts, lien waivers, daily logs
- Implement role-based access control (RBAC) with multi-level permissions across user types
- Build document management with version control, cloud storage (AWS S3), full-text search, and large file handling (100+ MB)
- Set up cloud infrastructure (AWS/Azure/GCP): auto-scaling, load balancing, Docker/Kubernetes, CI/CD pipelines
- Build third-party integrations (QuickBooks, Sage, DocuSign, scheduling/ERP systems)
- Develop mobile functionality via React Native, Flutter, or PWA with offline capability

Requirements
- 5+ years professional software development experience
- Proven track record taking a product from concept to live production deployment
- Experience with multi-tenant SaaS or enterprise platform architecture
- Strong full-stack skills: modern front-end frameworks, server-side languages, relational databases
- Deep system design and architecture understanding
- Cloud platform experience (AWS/Azure/GCP) including DevOps, CI/CD, and containerization
- Strong security fundamentals: OAuth 2.0, JWT, RBAC implementation
- Experience with API development, third-party integrations, and data conflict resolution
- Ability to work independently and communicate clearly to non-technical leadership
- Bias toward action — ship and iterate over endless planning

Nice to Have
- Construction tech, project management platforms, or B2B SaaS experience
- Mobile development (React Native, Flutter)
- Startup or small-team environment background
- Accounting system integrations (QuickBooks, Sage)
- Real-time dashboards or BI features
- Knowledge of construction workflows and field operations

What We Offer
- Ground-floor role with direct product and company impact
- Direct access to leadership with no management layers
- Full technical autonomy and ownership
- Competitive compensation with potential equity/profit-sharing
- Fast-paced environment that values results over process

Compensation: $100,000.00 - $130,000.00 per year
