Companies in hundreds of industries rely on frontline salesforces working in-person, yet they've operated with zero visibility into these critical customer interactions. Meanwhile, sales productivity follows a stark Pareto distribution – the vast majority of commissions accumulate to a small percentage of top performers, leaving millions of salespeople struggling to achieve financial freedom. Siro is democratizing sales excellence by capturing and analyzing in-person sales conversations.

Requirements

  • You have strong proficiency in modern programming languages, databases, API frameworks, and cloud platforms (like GCP)
  • You are a strong problem solver, with the ability to think critically and approach challenges with a first-principles mindset.

Responsibilities

  • Build platform and backend systems at Siro, across recording, integrations, AI agents, and more!
  • Own the end-to-end development of key features, from architectural decisions through implementation, deployment, and support
  • Design and build scalable backend services that handle real-time processing of sales conversations
  • Drive technical excellence through thoughtful code reviews, documentation, and engineering best practices
  • Partner closely with product and design teams to transform customer needs into elegant technical solutions
  • Own the health of our systems and products, and make data-driven decisions
  • Help evolve our development practices and tooling to enable sustainable scaling while maintaining velocity

Other

  • We expect 6+ years of professional software engineering experience.
  • You are excited to work in our NYC office 3+ days a week with the rest of the team.
  • You have strong communication skills, able to articulate complex technical concepts to both technical and non-technical stakeholders.
  • You're a collaborative team player with a "we before me" mindset, always ready to support and elevate your colleagues.
  • You have high standards for excellence and aren't afraid to voice your opinion to push for quality.
