What You'll Be Doing & Why It Matters

We’re looking for a Senior Software Engineer to take important, poorly defined internal problems and create a path to solving them. You’ll build tools and automate processes across Salesforce’s internal ecosystem, supporting our internal developer platform (including our feature flags and experimentation platform) and improving development and business workflows. You’ll work directly with the people experiencing the problem, decide what is worth building, and drive the cross-team decisions needed to ship it securely.

Core Responsibilities & Scope

  • Identify internal problems worth solving and turn them into well-scoped proposals with clear evidence of value.
  • Run product discovery: talk to affected users, test assumptions, choose a useful first scope, and define how we’ll know the change helped.
  • Drive stakeholder decisions, cross-team commitments, and dependencies when ownership or priorities are unclear.
  • Build security into what we deliver. Evaluate design choices against enterprise security expectations, weigh tradeoffs, and work with security and privacy reviewers through review and remediation.
  • Deliver software using AI-assisted engineering, and verify behavior through tests and other repeatable evidence.
  • Ship pilots and improvements, then follow through on adoption and iteration.
  • Raise the effectiveness of the team through code reviews, clear decisions, and practical improvements to how we work.


Minimum Requirements

  • 8+ years of professional software engineering experience, including owning production software from design through delivery and ongoing operation
  • Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
  • Autonomy through ambiguity: a track record of taking an initiative with unclear requirements or ownership and driving it to an outcome. You’ve found the decision-makers, clarified ownership, resolved dependencies, and brought options when escalation was needed.
  • Cross-team influence: experience leading work across teams you don’t manage, getting alignment and commitments without formal authority.
  • Product and engineering judgment: experience investigating real user workflows, validating assumptions with users, choosing a scope, and measuring whether the change worked.
  • Security fluency as a builder: real experience partnering with security teams on software you were delivering. You can distinguish design choices that meet enterprise security standards from those that don’t, evaluate tradeoffs, and apply threat modeling, authorization design, and secrets management.
  • Discerning use of AI: experience directing AI-assisted implementation, understanding and correcting its output, and verifying behavior through tests and other repeatable evidence.
  • Engineering craft: strong code review, automated testing, and delivery practices, with a habit of defining how success will be measured.
  • Communication: clear written and verbal communication, including the ability to write a persuasive proposal for technical and non-technical partners.
  • Raising others’ effectiveness: experience improving team practices through reviews, mentoring, or clear technical decisions.


Preferred Qualifications

  • Experience owning product discovery and delivery
  • Experience building enterprise software or internal tools
  • Experience working in security-conscious or regulated environments
  • Experience improving team effectiveness through AI-assisted workflows
