Senior Technical Lead/Technical Lead
About the role
Gapstars is seeking a Senior Technical Lead/Technical Lead to take independent ownership of complex features across their products, including web applications, backend services, cloud operations, and a forthcoming mobile application. The role involves full stack development using TypeScript, React, Next.js, Node.js, and PostgreSQL, as well as deploying and operating workloads on GCP and Kubernetes. The successful candidate will also be responsible for mobile app development and release, with a requirement for hands-on experience in submitting an app to the Apple App Store. The position emphasizes AI-assisted development, DevOps practices, and strong communication and quality ownership throughout the software lifecycle. Gapstars is a Netherlands-headquartered company with talent hubs in Sri Lanka and Portugal, working with European clients across various domains.
Must have
- 8+ years of professional software engineering experience, including substantial hands-on full stack development and independent ownership of complex production features and technical decisions.
- Strong hands-on TypeScript, React, Next.js, Node.js and relational database experience.
- Substantial practical experience deploying, operating and troubleshooting production applications on GCP.
- Hands-on Kubernetes experience beyond introductory courses or certification exercises.
- Practical Docker, CI/CD and DevOps experience, including safe deployment and recovery.
- Hands-on mobile application development experience using a production framework.
- Personal responsibility for submitting and successfully releasing at least one application to the Apple App Store. Candidates must explain their own role in build signing, submission, review feedback and release; mobile project participation alone is insufficient.
- Regular use of AI-assisted development tools, supported by concrete examples of directing, verifying and correcting generated work.
- Strong debugging, automated testing, security awareness, communication and independent delivery skills.
Nice to have
- Relevant GCP certifications supported by practical production experience.
- React Native and Google Play Store publishing experience.
- GKE, infrastructure as code, automated infrastructure provisioning and mobile CI/CD.
- Playwright, Jest, Vitest or equivalent testing tools.
- Background processing, queues and reliable third-party integrations.
- Production integration of LLM APIs or AI-powered features, including evaluation, privacy, error handling and cost controls.
- Enterprise platforms handling sensitive employee or business data.
- Experience with Rust or GoLang.
