Senior Platform Engineer $200,000 USD/year Pay is set based on global value, not the local market.
Most roles = hourly rate x 40 hrs x 50 weeks
Description
We are seeking Platform Architects to establish the foundational systems that enable other teams to build effectively. In this role, you will contribute to platform-level products where your decisions on APIs, architectural patterns, and documentation directly influence how multiple teams execute their development work.
Potential products include:
- TimeBack: Educational platform supporting Alpha School's 2-hour learning model (99th percentile test results)
- Incept: Content generation platform producing personalized educational content for various learning applications
- Crossover: AI-powered hiring platform managing tens of thousands of applicants monthly
- This position emphasizes design: 50% producing specs, API contracts, and technical decisions; 30% building complex platform features; 20% reviewing work and providing guidance. You hold technical authority over architectural choices. Once aligned with the team, your specifications become mandatory.
Collaborate with a small team of accomplished peers. High ownership, no bureaucracy. You design it, you implement it, you own it.
What you will be doing
- Producing specifications prior to implementation
- Creating APIs that ensure backward compatibility and extensibility
- Recording Important Technical Decisions (ITDs) with supporting rationale
- Implementing complex platform features
- Conducting PR reviews to maintain architectural consistency
What you will NOT be doing
- Extensive team leadership or people management
- Development on straightforward app-level products
- Participating in endless meetings
- Pure architecture work without hands-on implementation
Candidate requirements
- A minimum of 5 years of professional software development experience
- At least 2 years designing systems where other teams relied on your APIs or architectural decisions
- Demonstrated history of authoring technical specs or technical decisions that were implemented by others
- Experience integrating AI tools into development workflow
