About Calo
Calo is a meal subscription startup on a mission to make healthy eating easy. Over the past six years, we've delivered tens of millions of meals to hundreds of thousands of customers across seven countries and we still feel like day one. Now, we're embarking on an AI-powered transformation to change how the world eats and make healthy meals better, faster, and more affordable.
Role Overview
As an AI Specialist, you'll be the hands-on engine powering our AI experiments and automations. You'll dive deep into the latest large language models, build and fine-tune agents, and craft workflows that solve real business problems. If you live and breathe prompt engineering, spend your weekends tinkering with new AI tools, and can't wait to prototype "just one more" idea, this is your playground.
Curious? No coding required. You don't need a programming background to excel in this role if you're passionate about AI and creative problem-solving; we'll teach you the rest.
What You'll Do
Agent Development & Prompt Engineering
1. Design, iterate, and optimize prompts for LLMs (ChatGPT, Claude, Gemini, etc.)
2. Build custom AI agents that automate tasks, surfacing data and insights in real time.
Proof-of-Concept Prototyping
3. Rapidly prototype ideas: from automated email assistants to intelligent analytics dashboards.
4. Collaborate with Product and Engineering to scope, test, and demo each POC.
Data Preparation & Model Tuning
5. Collect, clean, and structure data to steer API-based LLMs or fine-tune open-source models.
6. Monitor performance and iterate on training pipelines.
Cross-Functional Collaboration
7. Partner with business stakeholders to identify pain points and translate them into AI solutions.
8. Document your workflows and share best practices across the squad.
Knowledge Sharing & Tool Evangelism
9. Stay up to date on emerging AI tools and techniques.
10. Lead internal "lunch & learn" sessions to spread AI fluency across Calo.
What You Bring
11. AI Obsession: You've spent 10+ hours a day experimenting with ChatGPT, Claude, Gemini, or any other new model you can get your hands on.
12. Prompt Engineering Skills: You know how to coax the best answers out of black-box models and can teach others to do the same.
13. Rapid Prototyping Mindset: You love hacking together MVPs and learning from every iteration.
14. Collaborative Spirit: You thrive in cross-functional teams and can communicate complex AI concepts to non-technical partners.
15. Growth Attitude: You embrace ambiguity—100 problems at once? You're excited by the challenge of choosing the top 3 that'll move the needle.
Nice to Have
16. Familiarity with Python and working with APIs (OpenAI, Anthropic, Google).
17. Experience fine-tuning or training open-source LLMs (e.g., using Hugging Face).
18. Background in automation frameworks (e.g., Zapier, n8n, Airflow).
19. Familiarity with cloud platforms (AWS, GCP, or Azure) for production deployments.
Application Process
To help us see your creative spark and hands-on skills, please choose one of the following project prompts (or surprise us with your own idea), and submit:
1. WhatsApp Personal Chef Bot
Build a flow where users message their personal chef, and the backend routes instructions to a chef's dashboard with meal prep details.
2. Smart Delivery ETA Checker
Create an agent that tracks driver locations and dynamically calculates ETAs based on remaining stops.
3. Automated Content Creator
Search through customer support chats to find fun stories, then turn them into content pieces—initially as blog posts and later as short-form videos that can be auto-posted to social media.
4. Your Own AI-Driven Idea
Pitch and prototype any AI automation or agent that could add value to a subscription business like Calo.
What to Submit:
20. A 1-minute video walkthrough or demo link (YouTube, Loom, etc.)
21. A PDF or shared doc containing your designs, prompts, code snippets, or PRD
22. Your CV or LinkedIn profile link
