• Identifying and helping remove technical and delivery impediments 
• Contributing to and fostering a vibrant technical community 

Through Mob Way, you will be supported to grow your career while staying connected to culture. This includes strong executive connection, opportunities to build your networks, and dedicated time for in‑community experiences and elder‑led cultural immersion. 

 What do I need?

• Familiarity with SaaS technologies such as Kafka or MongoDB (desirable)
• Practical experience applying AI/LLMs in production environments (e.g. RAG, prompt/tool design, model integration), including testing and responsible AI practices (desirable)  

Why join us? 

As part of Mob Way, you will receive tailored career support through executive coaching, culturally safe leadership development, and opportunities to strengthen your connection to community and culture.
