This role involves collaborating with cross-functional teams to ensure performance, security, and reliability while modernizing the codebase. ## Job description Field sales powers the economy — but most teams are struggling. Reps are buried in admin work, managers are stretched thin, and leaders can’t see what’s really happening in the field. Siro is redefining how field sales teams learn, perform, and win. We started as an AI-powered coaching platform that helped reps improve their outcomes in the field. Today, we’re something much bigger — an intelligent companion that automates sales reps’ tedious admin work, gives managers real-time visibility, and helps executives see around corners. Our platform integrates with systems like Salesforce, analyzing thousands of in-person sales conversations to surface insights, automate workflows, and drive better outcomes across the org. Think Iron Man’s Jarvis for sales — proactive, personalized, and built directly into the tools teams already use. Siro has raised $75M and is backed by world-class investors like Index, Fika, CRV, and SignalFire. We are trusted by leading home-improvement, retail, hospitality, and automotive brands, and powered by a lean team from Meta, McKinsey, Doordash, and Uber. We’re building the future of human-AI collaboration in sales — and we’re just getting started. ## Key Responsibilities - Contribute to the development, improvement, and long-term architecture of our React Native mobile application across iOS and Android. - Own core feature delivery end-to-end in React Native, from technical design to implementation and release. - Collaborate closely with product, design, and backend teams to translate requirements into reliable, scalable app experiences. - Maintain, refine, and modernize our existing React Native codebase, with an eye toward performance, stability, and long-term maintainability. - Uphold code quality through reviews, testing, documentation, and collaboration with fellow engineers. - Ensure application performance, reliability, and security standards are consistently met. - Contribute to continuous improvement of our engineering practices and mobile development processes. - Stay updated with emerging best practices in mobile and React Native development, and introduce improvements where beneficial. ## Requirements - You have deep expertise in React Native (6+ years of experience, with multiple meaningful production deployments). - You have hands-on experience maintaining and scaling existing React Native applications, not just greenfield builds. - You are comfortable working in Swift and/or Kotlin when needed to extend or augment React Native functionality (supplementary/native skill, not primary focus). - You have demonstrated experience leading technical initiatives, owning projects, and working with high performing engineering teams. - You are well-versed in mobile engineering best practices, including performance optimization, security, testing, and release management. - You have experience creating and implementing Git-based workflows and CI/CD pipelines for mobile app releases. - You demonstrate strong problem-solving and communication skills, and can clearly articulate tradeoffs and technical decisions. 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 At Siro, we are committed to creating a diverse and inclusive environment where all people feel that they are equally respected and valued, whether they are applying for an open position or working at the company. We provide equal employment opportunities to all applicants without regard to race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status. ## About Siro ## Company Overview - **One-liner**: Siro builds an AI-powered platform that records, transcribes, and analyzes in-person sales conversations to provide coaching, automate admin work, and surface strategic insights for field sales teams. - **Entity Type**: Private (Series B) - **Headquarters**: New York, New York, United States - **Founded**: 2020 - **Founders**: Jake Cronin ## Core Business - **Industry**: Sales Intelligence / AI-powered Conversation Intelligence - **Target Customers**: B2B – field sales teams in home improvement, retail, distribution, hospitality, and automotive sectors - **Mission**: “To make in-person sales the most empowered, data-driven, and coachable aspect of any business” and “rewire the trillion-dollar world of in-person sales by turning every customer conversation into winning insights.” ## Products & Services - **Siro Platform**: An intelligent sales companion (often described as “Iron Man’s Jarvis for sales”) that captures and analyzes in-person conversations via mobile/audio, integrates deeply with Salesforce, automates CRM workflows, and provides real-time coaching, performance dashboards, and trend analysis.
