About the role

We're looking for a Staff Software Engineer to help build shared, API-first product platforms at AlphaSense that power multiple product surfaces, integrations, and agentic workflows. In this role, you'll focus on building platforms as products: well-designed APIs, clear contracts, strong reliability guarantees, and delivery driven by real product needs. These platforms are consumed by internal product teams and external integrations, including AI agents. This role sits at the intersection of hands-on engineering and technical leadership within the team. You'll stay close to the code while helping shape how product platforms are designed, evolved, and adopted. You'll collaborate across teams and own end-to-end systems within your domain. This is not a people-management role, nor a purely advisory architecture role. We're looking for a Staff engineer who enjoys building, prototyping, iterating, and solving complex problems in production.

Responsibilities

  • Serve as a technical owner for API-first systems within your team and domain
  • Design, build, and evolve high-scale APIs used by internal teams, external customers, and intelligent agents
  • Apply API governance, versioning strategies, and backward compatibility in your systems
  • Contribute to API standards, design principles, and best practices through hands-on work and technical reviews
  • Tackle complex problems where requirements are ambiguous and constraints are real
  • Partner with Product, Platform, and SRE teams to ensure APIs are reliable, observable, secure, and scalable
  • Identify and reduce technical risks within your domain
  • Mentor engineers and raise the technical bar through example

Requirements

  • Significant experience as a senior or staff-level software engineer working on applications and backend systems
  • Experience building product platforms or shared services consumed by multiple teams
  • Track record of designing, building, and operating APIs at scale
  • Strong hands-on experience with RESTful APIs
  • Some experience with GraphQL (design, usage, or operating in production)
  • Solid understanding of system design, performance, reliability, and evolution over time
  • Strong bias toward hands-on contribution and ownership of real systems
  • Ability to influence technical direction within and across teams through credibility and execution
  • Experience building or enabling agentic or AI-driven workflows
  • Familiarity with MCP (Model Context Protocol) or similar agent integration patterns
  • Experience working in large-scale, distributed systems environments
  • Experience working closely with platform and SRE teams
