Description
We are seeking Platform Architects to establish the foundational systems on which other teams rely. In this role, you will focus on platform-level products where your architectural patterns, API design choices, and documentation influence the development approach of multiple teams.
Potential product areas include:
- TimeBack: Educational platform that supports Alpha School's 2-hour learning model (99th percentile test results)
- Incept: Content generation platform that produces personalized educational content for various learning applications
- Crossover: AI-powered hiring platform managing tens of thousands of applicants each month
- This role emphasizes design: 50% creating specifications, API contracts, and technical decisions; 30% building complex platform features; 20% reviewing and guiding team members. You hold technical authority over architectural choices. Once alignment is reached with the team, your specifications become mandatory.
You will work with a small team of skilled peers, enjoy high ownership, and face no bureaucracy. You design it, you build it, you own it.
What you will be doing
- Creating specifications prior to implementation
- Architecting APIs for backward compatibility and extensibility
- Producing Important Technical Decision (ITD) documents with supporting rationale
- Implementing complex platform features
- Conducting PR reviews to ensure architectural consistency
What you will NOT be doing
- Extensive team leadership or people management responsibilities
- Development of simple app-level products
- Participation in endless meetings
- Pure architectural work without hands-on implementation
Candidate requirements
- Minimum of 5 years of professional software development experience
- At least 2 years of experience designing systems where other teams consumed your APIs or relied on your architectural decisions
- Demonstrated history of authoring technical specifications or technical decisions that were implemented by others
- Practical experience using AI tools in your development workflow
