Full Stack Engineer

The role

You will work across mobile, web, backend and cloud infrastructure. This is not a narrow ticket-execution role: you will understand the user problem, shape requirements, make sound architectural decisions and ship complete features into production in close collaboration with the founder, product, design, AI/video and business teams.

What you will own

Product engineering

• Translate product ideas and business requirements into clear technical plans, milestones and production-ready features.
• Own features end to end: discovery, technical design, implementation, testing, release, monitoring and iteration.
• Balance speed with maintainability, security, scalability and a high-quality user experience.
• Contribute product judgment—not only code—by identifying edge cases, simplifying flows and recommending better solutions.

FULL STACK DEVELOPER

Mobile and web experiences

• Build and maintain the consumer mobile application in Flutter, including camera access, video capture and upload, challenge participation, profiles, rewards, notifications and leaderboards.
• Develop responsive web applications and dashboards using React/Next.js for enterprise users, administrators, creators and brand partners.
• Turn designs into polished, intuitive interfaces with strong attention to layout, motion, responsiveness, accessibility and consistency.
• Improve application performance across device types, browsers, network conditions and large media files.

Backend, data and platform architecture

• Design and develop secure, well-structured services and APIs using Node.js/TypeScript; experience with NestJS is preferred.
• Build data models and high-performance workflows using PostgreSQL, an ORM such as Prisma, Redis and background job queues.
• Implement authentication, role-based access, permissions, auditability, webhooks and third-party integrations.
• Support real-time and high-engagement features such as scoring updates, leaderboards, notifications, moderation and campaign analytics.
  
• Design for multi-tenant enterprise use, data isolation, reliability and increasing volumes of users, campaigns and video assets.

AI and video workflows

• Integrate AI services for video scoring and analysis, avatar generation, voice, language, personalisation and content generation.
• Build resilient video ingestion, validation, storage, transcoding, rendering and delivery workflows using object storage, FFmpeg or related media services.
• Create asynchronous processing pipelines with queues, retries, progress states, fallbacks and cost-aware API usage.
• Help improve trust and safety through moderation, fraud detection, duplicate or manipulated-content checks and clear human-review paths.

Engineering quality and operations

• Set up and improve automated testing, code review, CI/CD, observability, error tracking, logging and production alerts.
• Deploy and operate services on a major cloud platform using containers and well-managed environments.
• Diagnose production issues quickly and improve performance, resilience, security and developer efficiency over time.
• Maintain clear technical documentation and communicate progress, trade-offs and risks to technical and non-technical stakeholders.

What we are looking for:

• 3–6 years of hands-on experience building and shipping full-stack products.
• Strong Flutter and Dart capability for production mobile applications.
• Strong proficiency in JavaScript/TypeScript, React or Next.js, Node.js and modern API development.
• Solid experience with PostgreSQL, data modelling, caching, queues and performance optimisation.
• Experience integrating third-party APIs, SDKs, cloud storage and external services reliably.
• Comfort with Docker, Git, CI/CD and at least one major cloud platform such as AWS, GCP or Azure.
• A strong grasp of application security, authentication, permissions, privacy and responsible handling of user and enterprise data.
• Product-management ability: you can break down ambiguous requirements, prioritise, estimate and drive work to completion.
• Excellent communication skills: you can explain decisions clearly, surface risks early and collaborate constructively.
• A strong aesthetic sense and genuine care for interaction quality, visual polish and the details users notice.
• High ownership, curiosity and comfort working in an entrepreneurial environment where priorities can evolve quickly.

Good to have:

• Experience with media-heavy applications, video processing, streaming, transcoding or rendering pipelines.
• Experience with AI/ML APIs, multimodal models, recommendation or scoring systems, or human-in-the-loop evaluation.
• Experience building gamification, social, creator, rewards, leaderboard or high-concurrency consumer features.
• Experience with multi-tenant SaaS, enterprise integrations, analytics dashboards and role-based administration.
• Familiarity with WebSockets, event-driven architecture, serverless services, content moderation or app-store releases.

How success will be measured

• Features move from concept to production with clear scope, sound engineering and predictable follow-through.
• The mobile and web experiences feel fast, intuitive and visually refined.
• Video and AI workflows remain reliable despite large files, asynchronous processing and third-party dependencies.
• The platforms become easier to operate, monitor, secure and scale with every release.
• Technical decisions and risks are documented and communicated before they become blockers.
