Job Description

Superside is looking for a Senior Fullstack Engineer to join our Staffing team. Our goal is to ensure the right creative talent is matched to the right projects in an automated way. This drives delivery and service quality for our customers by having the right creative talent matched to the right project in a predictable manner.

Throughout 2026 we are moving from manual allocation to automated, AI-assisted staffing at scale. You’ll be building interfaces and business logic in our internal tools that make it easy to manage availability and to match people and skills to projects in the best way.

We are looking for a builder who is proficient working across the entire stack, with a focus on the Frontend. You are a modern engineer that knows how to choose the right tool for any given job and feels comfortable across multiple programming languages and domains. You know when and where to leverage AI tools to move faster, but have the expertise to stay in control and implement things manually when that’s the best option.

What You’ll Do

• Lead the development of secure, scalable features focused on staffing automation, resource management, and complex scheduling interfaces.

• Architect and build performant UIs (e.g., interactive timelines, real-time grids) using React, while ensuring the backend logic (Kotlin/Spring) supports them efficiently.

• Use agentic coding tools to accelerate boilerplate and refactoring, allowing you to focus on high-leverage architectural decisions.

• Collaborate cross-functionally with Product and Design to identify manual staffing workflows and turn them into seamless software experiences.

• Enhance system performance through UI optimizations (rendering large datasets) and database improvements.

• Drive technical strategy and best practices, specifically regarding how we visualize complex data for our operations team.

What You'll Need to Succed

• 6+ years of full stack development experience, with strong expertise in FE framework. Superside uses React on the FE and Kotlin with Spring Boot on the BE, so these are beneficial.
• Strong understanding of software architecture, design patterns, and scalable system development.
• Deep knowledge of testing strategies, including unit, functional, and end-to-end testing. You know where, when and how to test a feature.
• Ability to solve complex technical challenges creatively and efficiently.
• Self-motivated and autonomous, with a proactive, problem-solving mindset with fluency in English (verbal and written).
• Excitement for AI-powered product development, with a desire to integrate AI-driven automation into creative workflows.
• Proactive use of agentic coding tools as part of your workflow, while always staying accountable and in control of your output and contributions
