About Instalily

InstaLILY is coming to London. We're bringing New York AI energy to your city - and it's going to be electric!

Backed by Insight Partners ($25M Series A) and supported by the Google, NVIDIA, and Microsoft ecosystems, we’re a New York based AI startup working at the cutting-edge of agentic AI. We’re now setting up a brand new engineering and sales hub here in London. If you’re excited by this chance to help shape a brand-new hub for AI and agentic innovation in London, and want to work on autonomous agents at the frontier of enterprise software, machine intelligence and human-AI collaboration - this is it - this is that opportunity of a lifetime.

As a Software Engineer at InstaLILY, you will be joining an extraordinary team headquartered in New York, and drawn from top-tier native AI talent from leading universities in the US including Princeton, MIT, Penn, Berkeley, Chicago and Cornell. You will be responsible for developing our AI Agents platform and driving technical excellence throughout the organization. You will work closely with the Lead Software Engineer and cross-functional teams to design and implement new features and capabilities. Additionally, you will be responsible for building a culture of continuous learning and improvement as we continue to build the Instalily team. You will benefit from world-class mentorship from highly-regarded executive leaders at the world’s most iconic brands.

Responsibilities

  • Continue to develop the core AI platform and drive technical excellence throughout the organization.
  • Work closely with cross-functional teams (product, UI/UX, business development) to design and implement new features and capabilities.
  • Rapidly learn into the expected quality and reliability of the platform through comprehensive testing and continuous integration/continuous delivery (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 degree in computer science, engineering, Mathematics, Physics or a related field.
  • First Class degree preferred.
  • Ability to start full-time by July 2025 (and onwards).
  • 0 to 2 years of experience as a software engineer (prior software engineering internships and experience/projects a significant plus).
  • Passion for understanding AI and machine learning technologies.
  • Experience with Python, JavaScript, and other programming languages.
  • Understanding of cloud computing technologies OR experience with AWS, Azure, or GCP.
  • Excellent problem-solving and analytical skills.
  • Track record of delivering successful products / working in a collaborative, fast-paced environment is a plus.

What You'll Get

  • Real traction: The product works, customers are live, and we've already driven over $200M in incremental revenue for customers — this isn't a bet on an unproven thesis.
  • Deep partnerships: Backed by Insight Partners with deep ecosystem partnerships across Google, NVIDIA, and Microsoft. InstaLILY's architecture has been featured in Google DeepMind's case study showcase.
  • Customer impact: You'll drive measurable operational change inside the customers you own.
  • Stage: Early enough to shape how InstaLILY runs customer relationships and expansion at scale.
  • Culture: Offices in New York, San Francisco, and London — sharp, low-ego team moving fast.
  • Growth: The learning curve is steep

Compensation and Benefits

  • Salary Range : 48,000 - 56,000GBP per year, commensurate with experience
  • Equity : Generous stock options awards, and refreshers for top performers
  • Benefits: Supplemental benefits, pension contribution, in-office Lunch reimbursement, Wellbeing Stipend, Generous Parental leave, PTO and UK National Holidays, and more!

Join the AI revolution with InstaLILY! As a Software Engineer, you will have the opportunity to make a significant impact on the future of AI and work with a talented and passionate team of experts. If you’ve ever wanted to be part of building something enduring from the start — not a role, but a culture — this is that moment. We’re proud to open in London, and we’re looking for world-class minds to build with us. If that sounds like you, you are exactly who we want to hear from.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
