About Lif3away

Lif3away is building an AI-native platform reimagining the medium- and long-term rental experience.

Our goal is to simplify and unify the rental journey through intelligent workflows powered by conversational AI, enabling a more seamless experience for both property operators and renters.

We are currently preparing for our upcoming Closed Beta launch, beginning in select major cities.

The platform is already in place.

Now we're focused on refining it for a reliable production launch.

The opportunity

We're looking for a
Senior Full Stack Engineer
to join our core engineering team.

This is not a traditional feature-development role.

Your primary mission will be helping us transform an ambitious AI product into a stable, reliable production platform capable of serving real users.

You'll work directly with the Founder and our engineering team to remove critical blockers, improve system reliability, and prepare Lif3away for launch.

• Strengthening conversational memory and state management
• Eliminating workflow regressions
• Improving listing creation reliability
• Improving search quality and relevance
• Increasing backend stability
• Optimizing performance
• Strengthening testing and release confidence
• Helping deliver a production-ready MVP

Success means users can complete the entire rental journey with confidence and reliability.

• Experience designing scalable backend APIs
• Experience shipping production SaaS applications
• Excellent debugging and root cause analysis skills
• Strong understanding of system architecture
• Experience working across frontend and backend
• Experience working with cloud infrastructure
• Ability to independently own technical problems from investigation through deployment
• Strong communication skills
• Product-oriented mindset

Strong plus

Experience with

• AI-enabled applications

• Tool calling
• Conversational AI
• Prompt engineering
• Structured outputs
• Retrieval-Augmented Generation (RAG)
• Vector databases
• PostgreSQL / pgvector

What success looks like

Within your first weeks, you'll help us achieve:

• Stable conversational memory
• Reliable listing creation
• Reliable search experience
• Reliable booking workflows
• Reduced production regressions
• Faster debugging and issue resolution
• Improved platform performance
• High-confidence production releases
• A successful Closed Beta launch

What we value

We're less interested in titles than in how you work.

We value engineers who:

• Take ownership
• Solve problems end-to-end
• Care about quality
• Ship production-ready software
• Think from the user's perspective
• Communicate clearly
• Enjoy debugging complex systems
• Thrive in fast-moving startup environments

Compensation

• Competitive equity package
• Equity-first compensation during our current bootstrap phase
• Transition to a competitive salary, while maintaining equity participation, once the company reaches sustainable operating scale
• Fully remote
• Flexible working environment
• High ownership and meaningful technical influence

Why join Lif3away?

This is an opportunity to join at one of the most important moments in our company's journey.

You'll help shape the engineering foundation of an AI-native platform before launch, working directly with the founder and a small, highly collaborative team.

If you enjoy building ambitious products, solving difficult technical challenges, and turning innovative ideas into reliable production systems, we'd love to hear from you.
