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.
Job Responsibility:
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
Identify repeatable patterns across engagements and help codify them into reusable solutions and platforms
Requirements:
6+ years of full stack development experience, with strong expertise in FE framework
Strong understanding of software architecture, design patterns, and scalable system development
Deep knowledge of testing strategies, including unit, functional, and end-to-end testing
Ability to solve complex technical challenges creatively and efficiently
Excellent communication skills with fluency in English (verbal and written)
Self-motivated and autonomous, with a proactive, problem-solving mindset
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
Nice to have:
Superside uses React on the FE and Kotlin with Spring Boot on the BE, so these are beneficial
What we offer:
Remote-first work
Global community spanning 60+ countries
Fast-paced, high-energy environment with truth-seeking teammates
Trust, collaboration, and continuous learning
Influence our product like a startup while enjoying the stability of a thriving scale-up
