Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of AlphaSense as an employer.

What you need

  • Deep production backend and distributed-systems expertise, including service boundaries, data ownership, consistency, failure recovery, and integration models.
  • Strong hands-on engineering experience, with significant personal contributions to production code and system evolution.
  • Experience designing client-facing REST and GraphQL APIs, with sound judgment about business-logic placement, product states, and backward compatibility.
  • Strong understanding of authentication, authorization, entitlements, and session management, including trust boundaries and the security implications of client-service interactions.
  • Experience improving customer-visible reliability and performance across client and backend systems, with practical expertise in observability and production validation.
  • A track record of leading consequential technical change across teams through influence rather than reporting authority.

Nice to have

  • Experience building production systems for AI-powered search, research, or analysis workflows.
  • Experience with enterprise identity and managed applications, such as Auth0, Microsoft identity, or MDM/MAM ecosystems.
  • Experience designing shared configuration or service discovery for multi-tenant platforms and dedicated customer environments.
  • Experience designing and building event-driven systems, including publish/subscribe or event-streaming architectures such as Kafka.

Worth weighing

  • No salary listed.
  • The role involves significant cross-team collaboration and influence rather than direct authority, which may require strong interpersonal skills.
  • Prior iOS or Android experience is not required, which may appeal to candidates focused solely on backend development.
