InstaLILY is a New York-based AI startup working at the cutting-edge of agentic AI. We build autonomous agents at the frontier of enterprise software, machine intelligence, and human-AI collaboration.
As a Software Engineer at InstaLILY, you’ll join a team drawn from top-tier university programs. You’ll develop our AI agents platform and drive technical excellence across the org. You’ll work closely with the Lead Software Engineer and cross-functional teams to design and implement new features and capabilities, and help build a culture of continuous learning as we grow.
This role is client-facing. You’ll build and ship AI agents that operate inside our customers’ systems, and you’ll be in regular working sessions with stakeholders at enterprise customers. You need to code at a high bar and communicate decisions clearly.
Responsibilities
- Develop InstaLILY’s AI platform and drive technical excellence throughout the organization
- Work closely with cross-functional teams (product, UI/UX, business development, growth) and key business stakeholders to design and implement new features and capabilities
- Partner with the Growth team during customer deployments: understand workflows, defend architectural decisions, and iterate on feedback
- Raise quality and reliability through comprehensive testing and CI/CD practices
- Build a rapport with the Lead Software Engineer and Head of Product while fostering a culture of continuous learning and improvement
- Collaborate with the product and design teams to deliver high-quality products that meet customer needs
- Stay up-to-date with the latest AI and software engineering trends and technologies
Requirements
- Bachelor’s in CS, engineering, math, physics, or related: demonstrated ability matters more than credential
- 0–2 years as a software engineer (strong candidates have shipped something with real users)
- Strong fluency in at least one backend language (Python, TypeScript, or similar) and a modern web stack
- AI-serious: you’ve built something with LLMs (a RAG system, an agent, a fine-tuned model, a real integration)
- Strong communication: you can explain what you built and why you built it that way to non-technical audiences
- Strong problem-solving and analytical thinking
What You’ll Get
- Proven product: Customers are live; this isn’t a bet on an unproven thesis
- AI-native: In how we build, how we work, and what we sell
- Stage: Early enough to shape how the company scales
- Global: Based in-person in New York with offices in SF and London
- Culture: Sharp, low-ego team that keeps raising the bar
- Growth: The learning curve is steep
Join InstaLILY and build autonomous agents that matter. If you want a role where your code ships into real enterprise systems and where you’re in the room with customers, we want to hear from you.

What We Do
Humans + InstaLILY = Superhumans. That is our mission at InstaLILY AI: to pair every person with an AI teammate who makes work faster, smarter, and more human. Our InstaWorkers™ are not bots or dashboards. They are better software — blending AI and code to create Code-as-Work, the ability to turn business workflows into bits and bytes that run themselves. InstaWorkers™ are already deployed at some of the world’s most demanding companies. They log into Salesforce, SAP, and ERPs to handle quoting, follow-ups, claims, and backlogs across the complex distribution economy — from physical goods to insurance policies to industrial parts. With Instalily, work is not just automated, it is codified. That means fewer delays, fewer errors, and more time for people to do what only humans can: sell, solve, and lead. We are an elite team of dreamers and doers based in New York City, united by one belief: when work becomes code, humans become superhuman.
