As a Senior Frontend Developer, you will architect and build frontend systems, collaborate with clients, and champion engineering best practices while working in a cross-functional team.
About us
Appnovation is a global, full-service digital partner that combines Strategy, Experience & Design, Engineering and Managed Services. We build digital solutions that deliver real impact today and serve as foundations for future growth. Bold ambition. Practical action. Endless possibilities.
As a Senior Associate Engineer, you will join a highly motivated, experienced team building web and mobile applications while providing strategy consulting for Appnovation's clients. With a strong bias toward frontend craft, you will bring modern React and Next.js to life and turn business ideas into polished, production-ready interfaces. We are looking for engineers who pair sharp technical instincts with a consulting and solution-focused mindset, people who can sit with a client, understand the problem, and ship the right answer.
Key Responsibilities:
- Architect and build frontend systems using Next.js 15 (App Router, RSC, SSR/SSG), React 19, TypeScript, and Tailwind CSS.
- Build and maintain component libraries with shadcn/ui, including theming via CSS variables and multi-locale support (en, zh-hk, zh-cn).
- Contribute to the React Native (Expo) mobile app, sharing a content layer with web through an internal UI package.
- Integrate frontend with a Strapi v5 headless CMS and a Flask/Python API, working with AWS Cognito for auth and DynamoDB for application data.
- Translate design systems and product requirements into reusable, scalable interfaces.
- Partner with clients to shape technical direction and deliver enterprise-grade applications.
- Champion engineering best practices across code quality, testing, and continuous delivery.
- Collaborate closely with designers, backend engineers, and product managers in a cross-functional environment.
What we are looking for
Must-Have:
- 8+ years of experience as a software developer or in a comparable engineering role.
- Strong experience building frontend architectures with Next.js (App Router, RSC, SSR/SSG), React, and Tailwind CSS.
- Proficiency with modern JavaScript and TypeScript (TypeScript 5 preferred).
- Experience building cross-platform mobile apps with React Native and Expo (Expo Router, file-based navigation).
- Hands-on experience with relational and NoSQL databases (PostgreSQL, DynamoDB, SQLite, or equivalents).
- Experience integrating with headless CMS platforms, ideally Strapi v5, including Draft & Publish workflows and i18n.
- Experience with AWS services in production (Cognito, DynamoDB, S3, ECS, ECR).
- Experience with end-to-end and component testing using Playwright, Cucumber (BDD), and Storybook, alongside unit testing and TDD practices.
- Comfort with continuous delivery tooling and practices (GitHub, Vercel deployments, agile workflows).
- Experience designing, orchestrating, and deploying container-based solutions with Docker, and infrastructure-as-code with Terraform.
- Working knowledge of agile methodologies (Scrum, Kanban) and operating in a DevOps environment.
- Strong written and spoken English.
- Availability to commit to a full-time, six-month contractor engagement.
Nice-to-Have:
- Experience with real-time features using Socket.io.
- Experience integrating AI services such as ElevenLabs for voice generation.
- Experience with Strapi Cloud deployments.
- Experience working in WSL2 environments.
- Prior consulting experience.
Who you are
- You think in systems. You build for scale, automation, and long-term operability, not just the problem in front of you.
- You hold a high bar for code quality, performance, and security, and you raise it as you go.
- You bring sharp analytical instincts and sound judgment to ambiguous problems.
- You lead with a customer-first mindset and treat client relationships as partnerships worth investing in.
- You communicate clearly and influence effectively across every level of an organization.
- You thrive in fast-moving, high-performance environments where priorities shift and the work matters.
- You step into the unfamiliar willingly, and you pick up new concepts, tools, and business models quickly.
