Senior Software Engineer - AI / ML

CALLING ALL GLOBAL SENIOR SOFTWARE ENGINEERS WITH AI / ML & VOICE AI EXPERIENCE

About Sophiie AI

Sophiie AI is transforming how service-based businesses operate. We’re building an AI Office Manager that takes care of the work no one has time for! From answering calls and booking jobs to quoting, scheduling, and invoicing.

In under 12 months, we’ve gone from $0 to 7-figure ARR, backed by some of Australia’s top early-stage VCs and already trusted by hundreds of businesses. We’re scaling fast, handling thousands of calls and interactions every week, and building the category-defining AI platform for the services sector.

With real customers, real revenue, and a product solving real problems, this is your chance to join a rocket ship right as it’s taking off.

The Role

We’re looking for a Senior Software Engineer to help us push the boundaries of applied artificial intelligence in real-world, customer-facing products.

You’ll work on systems that power intelligent conversations, context-aware automation, and lightning-fast decision-making. Some of this involves voice, some text, and some pure machine learning magic, but all of it must be production-ready, scalable, and delightful to use.

This isn’t a research lab role; it’s about shipping robust, high-performance systems that directly power thousands of real-world interactions every day. You’ll have huge ownership, move fast, and see your work have an immediate impact on a rapidly growing customer base.

About You

• 5–8 years of experience as a software engineer, with significant exposure to AI / ML systems in production
• Strong Python skills, including async / await, error handling, and writing maintainable, production-grade code
• Experience with cloud-native deployment (Docker, AWS) and data infrastructure (SQL / NoSQL, Redis)
• Comfortable optimising for performance, cost, and reliability in high-traffic environments
• Experience with real-time communication tools like LiveKit, WebRTC, or SIP telephony
