Lagos, Lagos, Nigeria Crossover Full time

We operate platforms that serve thousands of students and teams worldwide:

  • TimeBack: Educational platform driving Alpha School's 2-hour learning model (99th percentile test results).
  • Incept: Content generation platform producing all personalized educational content for multiple learning applications deployed at Alpha School.
  • Crossover: AI-powered hiring platform handling tens of thousands of applicants per month, staffing schools and companies across the globe.

You will take ownership of one of these platforms and dedicate most of your time to building the most complex components of the codebase with a small team (3-5 strong engineers, no juniors). The architecture decisions you make will determine whether other teams can build new applications quickly, integrate seamlessly, and deliver value to students. Succeed here and you unlock massive leverage. Poor decisions lead to integration failures and destroy velocity across multiple teams.

You design, build, and operate your systems. You set quality standards and define patterns for your platform. We operate spec-driven: design precedes implementation, planning comes before building. High autonomy, no committees, no review boards. Tight-knit team structure, where you own what you deliver.

What You Will Be Doing

  • Technical Leadership: Drive strategic architectural decisions and define technical patterns for the team to adopt.
  • AI Leadership: Advance the adoption of new AI workflows and build high-impact playbooks.
  • Implementation: Develop the complex, high-stakes components of the codebase with your team.
  • Quality Reviews: Verify that your team adheres to established patterns and upholds quality standards.

What You Won't Be Doing

  • Serving as an architect without writing code
  • Spending time in endless meetings
  • Managing people (this is a technical leadership position, not a people management role)
  • Maintaining legacy systems or internal IT infrastructure

Basic Requirements
Senior Software Architect key responsibilities

  • At least 5 years of professional software development experience building software products
  • At least 3 years as either a lead engineer (reviewing others' work) or architect (making key technical decisions)
  • Experience working on platform-level products where other teams consumed your APIs
  • Deep engagement with AI tools, actively experimenting and pushing boundaries
