Hi, we are The Gradient — a human-first design agency for the AI era.

We believe we’re living through a software renaissance. The question is no longer “can this be built?” but “what should be built?”

The constraint has shifted from technical ability to clarity of intention. Truth reveals itself through building, not planning. The tools are ready. The real question: are you?
 

This role isn’t just about designing beautiful interfaces. It’s about understanding how AI systems behave, how front-end reality works, and how to turn invisible logic into clear, human-centered experiences.

If you’re excited by ambiguity, systems thinking, and building things that didn’t exist before — keep reading.
 

How we work

At The Gradient, we distinguish between principles of work and values:

• Principles are how we operate (e.g., build to learn, think in systems, no playbook).
• Values are deeper foundations — the base layer everything else runs on: Curiosity. Agency. Taste.
   

We look for three core qualities in people, not skills, years of experience, or portfolios. These are traits that can’t be taught: you either have them or you don’t. You can read more about our philosophy and what these mean in practice here.
 

What you’ll doDigital product design

• Own the design process from discovery to shipped experience.
• Design interfaces around AI systems, LLM outputs, and dynamic data.
• Turn messy business logic into structured, intuitive flows.
• Prototype quickly and iterate based on real system behavior.
   

Systems & technical thinking

• Design with awareness of components, states, APIs, and platform constraints.
• Understand trade-offs between frameworks (e.g. web vs mobile, Next.js vs React Native).
• Collaborate closely with engineers to ensure what you design ships in reality.
• Think in systems, not just screens.
   

AI-aware design

• Understand how LLMs behave: capabilities, limitations, edge cases.
• Navigate unpredictable outputs and hidden system logic.
• Design interfaces that support human—AI collaboration clearly and responsibly.
• Use AI tools to improve your workflow — but don’t treat them as black boxes.
   

Craft & detail

• Deliver high visual polish — aesthetics matter.
• Design real interaction depth: motion, transitions, hover states, loading states.
• Care about latency and perceived responsiveness.
• Sweat details most users won’t consciously notice — but will feel.
   

Collaboration

• Present and defend your work clearly.
• Co-create with strategists, engineers, and clients.
• Share new tools, experiments, and learnings.
• Raise the bar by questioning assumptions and exploring better solutions.
   

You’re a strong fit if you

• Have 3–5+ years of experience designing digital products end-to-end.
• Have shipped real products, not just concepts.
• Bring a portfolio with strong UX clarity and refined UI taste.
• Are comfortable working in ambiguity.
• Actively use AI tools and want to understand how they behave.
• Communicate clearly in English (Upper-Intermediate+).
• Love learning, experimenting, and helping others do the same.
   

What matters more than experience

We hire for values first:
Curiosity — You want to understand how tools and systems behave under the hood.
Agency — You don’t wait for detailed instructions. You see gaps and move.
Taste — You know what deserves attention — and what should be simplified.
 

Join Our Vision: We are building the next generation of Spatial Media - a new way people experience videos through interaction, multi-user presence, haptics, AI, and immersive storytelling.

DeoVR is the leading immersive streaming technology serving multiple enterprise customers and millions of users globally.

We are now expanding the boundaries of what video can be - moving from passive watching to active, interactive, multi-user journeys.

If this excites you more than it scares you, you are in the right place.
 

The Role

We are looking for a professional to join our web development team in the segment of a global VR video streaming ecosystem. The best measure of success for this role is when tasks meet their ends. All works as it should — smoothly, consistently, and reliably.
 

What You Will Do

• Develop and maintain server-side applications
• Collaborate with front-end developers to integrate user-facing elements
• Develop and optimize APIs for responsiveness and efficiency
• Improve database performance through indexing, caching, and query optimization
• Enhance code quality through unit and integration testing
• Debug issues and strengthen overall app reliability
• Participate in code reviews, daily stand-ups, sprint planning, and retrospectives

• Experience with Redis (nice-to-have)
• Experience with Golang is a significant plus
• English level B1+ (Intermediate+) or above
   

Hiring Process

• Team Interview (1 hour)
• Live Coding Interview (1 hour)
• CEO Interview (45 min)
   

What We Offer

• The chance to be part of a pioneering team in a rapidly evolving industry
• Direct impact on the future of immersive media
• Flexible working hours and remote-first culture
• A team that values initiative, clarity, and collaboration
• Access to all tools and tech you need
• Unlimited DeoVR Premium
• A work environment where ideas matter and people are treated with respect
