Job description

Alix is a VC-backed pre-seed startup, which focuses on bringing the latest AI innovation to pressing social problems. Primarily we work within the Social Housing industry, where there is LOTS of room to innovate.

Despite our young startup status, we have been finalists for National AI inclusion awards up against over 300 established players. Our clients include a leading disability charity and the UK’s largest Housing Association with 100,000 properties. We are revenue generating, and have an AI-forward platform, which integrates cutting-edge AI with WhatsApp to create easy-to-use powerful AI workflows. Through research-driven, co-design approaches, we strive to build ethical and impactful AI solutions.

The founders, Charisma and Bee, have worked in leading startups across London and beyond.

The role:

We are looking for a highly motivated mid-level full stack developer to join our growing team, targeting a “founding engineer” capacity. This role suits someone who likes end-to-end ownership and driving / owning multi-component systems. You should be comfortable navigating early-stage ambiguity, taking ownership, and jumping into messy code when needed. You will have worked in a couple of (early-stage) startups before. You will be working with our existing developer, and we have expansion plans within the next 12 months.

Key Responsibilities:

• Work closely with the founders to bring new products to life
• Own the development and deployment of AI-powered workflow solutions, and integrating them into the existing platform
• Stay up-to-date with the latest AI trends to enhance service offerings and proof-of-concepts
• Maintain and improve API integrations with messaging platforms like Twilio.
• Troubleshoot and debug technical issues to ensure smooth operations
• Contribute to existing frontend and backend applications as well as take on "greenfield" projects
• Can adapt to and enjoy working with early-stage startup iteration

Key Requirements:

• Startup experience
• 3 - 5 years career experience
• Willingness to learn
• Strong work ethic & attitude
• Strong problem-solving skills
• Experience with or strong interest in learning frameworks for building AI applications (i.e Langchain, Langgraph, Autogen, VertexAI, etc)
• Understanding of modern web communication protocols, including REST APIs, WebSockets, and webhooks
• Understanding of Git and GitHub for version control
• Decent understanding of databases (SQL or NoSQL) and cloud services (GCP)
• Ability to work in a fast-paced, startup environment and collaborate effectively.

Nice to Have:

• Exposure to WhatsApp API, Twilio, or similar communication platforms.
• Experience with deployment to cloud runtime environments (We use Cloud Run and App Engine)
• Experience having taken ownership of end-to-end systems
• Able to take abstract problems/product ideas and break them down into clear, actionable technical solutions
• Previous projects using any of our technologies or AI (either LLM APIs or frameworks)

What We Offer:

• Contract - Full time or 4 days a week
• Opportunity to work in a fast-growing AI startup with a mission-driven approach.
• Flexible hybrid work model (remote + London office).
• Our offices are based in Camden, and it would be great to see you 1-2 days a week in-person.
• Career growth and mentorship
• 'No bureaucracy" dynamic work environment.
• A lot of autonomy, minimal constraints on tools and technologies so you can experiment and take your professional development in any direction as you go
• Exposure to a wide range of technologies and opportunities to contribute beyond just code (i.e UX/UI design, communication design)
• Fast paced development environment, we push to "production" very frequently, it can be chaotic but you'll see your code live quickly!
• Play a key role in defining the company’s engineering culture and best practices

If you're passionate about AI and making a real impact, apply now to be a part of Project Alix!

High Level Interview process:

• 20-30 min first round call
• 60 min technical exercise / pair programming call
• 60 min in-person chat
