About this role
Founded in 2024, Momntum is revolutionizing customer service with AI that actually works. Our next-generation platform replaces outdated call centers with intelligent, omnichannel conversations that are fast, personal, and effective. At the core is our proprietary Relationship Language Model powering Laila - an AI chat assistant that connects across phone, WhatsApp, email and more.
We're already processing tens of millions of messages with an 85.4% success rate. Businesses like Sisu Clinic, Action24 and Peri are using Momntum to completely transform how they operate, with some seeing 4,000%+ ROI. We're not just a support tool - we're a growth engine.
Backed by Act Venture Capital and Sure Valley Ventures, we're disrupting an entire industry. Our founding team has felt the pain of broken customer service systems from both sides - as business owners and frustrated customers. Now we're building the solution.
As a Junior Developer, you'll be part of our core engineering team building the future of customer service. You'll work directly with our founders and senior engineers to develop and scale our AI platform, working on everything from our Relationship Language Model to our omnichannel integrations.
This is a rare opportunity to join a fast-growing startup at the ground floor, where your code will directly impact millions of customer interactions and help businesses transform their operations. You'll learn from experienced engineers while contributing to a product that's already generating massive ROI for our customers.
Key Responsibilities
Feature Development: Build and enhance features across our AI platform, from chat interfaces to backend integrations
API Integration: Develop connections with communication platforms like WhatsApp, Messenger, and email systems
AI/ML Support: Assist with implementing and optimizing our Relationship Language Model
Testing & Quality: Write tests and ensure code quality across our rapidly growing codebase
Customer Impact: Work on features that directly improve customer experience and business outcomes
Learning & Growth: Continuously develop your skills while contributing to our mission
What we're looking for:
1-3 years of development experience
Strong foundation in at least one programming language (Python, JavaScript, or similar)
Experience with web development frameworks
Basic understanding of APIs and database systems
Interest in AI/ML technologies
Startup mentality - scrappy, adaptable, and eager to learn
Strong problem-solving skills
Excellent communication and collaboration abilities
Passion for building products that solve real problems
Experience with customer-facing applications (preferred)
Familiarity with messaging platforms or communication tools (preferred)
At Momntum, we're disrupting an entire industry and we want people who aren't afraid to break things and build something better. If you're hesitating about applying, don't – we'd rather see your ambition than your perfect CV. We're a startup that believes the best ideas come from the most unexpected places, and we're building a team as bold as our mission to transform customer service forever.
Momntum provides equal employment opportunities to all employees and applicants for employment without regard to sex, race, colour, ethnic or social origin, genetic features, language, religion or belief, political or any other opinion, membership of a national minority, property, birth, disability, age or sexual orientation.
