Job description

We're transforming the trillion-dollar world of in-person sales by capturing and analyzing a never-before-digitized dataset: face-to-face conversations. While the tech world obsesses over digital interactions, most of our economy still runs on millions of in-person sales and service conversations happening daily across the U.S. Unlike Zoom calls, these conversations weren't historically recorded – leaving petabytes of rich data untapped. Until now.

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.

With Siro, we're democratizing sales excellence. Our customers see their reps closing up to 40% more deals, all while gaining unprecedented insights from field conversations.

We've built an intelligence platform that captures, processes, and derives actionable insights from in-person sales and service conversations. Our customers span diverse industries – home improvement, home services (HVAC, plumbing), retail, B2B distribution, insurance, hospitality, and more.

With over $75M in backing from world-class investors, we're on a mission to make field sales the most accessible path to financial freedom.

Our product is already making waves - 4.8 stars on the App Store (700+ ratings), 5.0 stars on G2 (25 reviews), and partnerships with industry leaders like ServiceTitan (NASDAQ: TTAN).

Key Responsibilities

• Build and enhance features (especially frontend) for Siro's direct consumers, creating intuitive user experiences for our AI-powered sales platform

• Own the end-to-end development of key features, from architectural decisions through implementation, deployment, and support

• Craft intuitive, performant user interfaces that make complex AI insights accessible to our users

• 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

• Help evolve our development practices and tooling to enable sustainable scaling while maintaining velocity

• Own the health of our systems and products, and make data-driven decisions

• Lead technical architecture for major initiatives. You'll help shape our technical strategy and advocate for developer productivity, system reliability, and more.

Requirements

• We expect 5+ 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 demonstrate strong proficiency in TypeScript frameworks

• You have experience with Node.js and REST API design

• You have demonstrated skill in mobile and/or web performance optimization

• You are a strong problem solver, with the ability to think critically and approach challenges with a first-principles mindset.

• You have strong communication skills, able to articulate complex technical concepts to both technical and non-technical stakeholders.

Our Tech Stack

In case you’re curious, we use the following technologies (and more), but proficiency in any specific technology is not required.

• Frontend: React Native, Svelte, TypeScript

• Mobile: Swift, Kotlin

• Backend: Node.js, Typescript, serverless functions

• Cloud: Google Cloud Platform (GCP)

• Other tools: Git, Datadog, Figma

Why Join Siro?

• Growth: Join a rapidly scaling Series B startup with proven product-market fit

• Technology: Work with cutting-edge AI technologies and a modern tech stack

• Team: Collaborate with an experienced CEO (previously built a successful sales tool used by 100,000+ reps) and top-tier team

• Ownership: Take end-to-end ownership of features that directly impact our users

• Learning: Work across the full stack and grow your technical breadth

• Impact: Help democratize sales success and create opportunities for millions of sales professionals
