Company Overview

Fuse is a high-growth New York City startup revolutionizing financial services infrastructure through an innovative low-code tool. Backed by top-tier venture capital, the company is creating a transformative self-service platform for configuration, integration, and automation in financial technology. We are now expanding our capabilities to leverage artificial intelligence in revolutionizing how financial services workflows and integrations are built.

Role Overview

We are looking for a Fullstack Solutions Engineer to join our development team. This is a fully technical role that requires strong programming fundamentals, the ability to work across both frontend and backend, and a focus on building reusable components.

You will be responsible for implementing solutions using our internal development tools, including Java-based visual code workflows and proprietary platforms built in-house. This role does not rely on a traditional IDE; instead, you will work directly within Fuse’s internal environments to build features, automations, and integrations.

We are seeking someone at a Mid-3 to Senior level, capable of working horizontally across multiple projects and collaborating closely with engineering teams.

Key Responsibilities

• Fullstack Development: Build, maintain, and optimize components across the frontend and backend using our internal tools.

• Component Building: Develop reusable components that power our internal modules and workflows.

• Technical Implementation: Design and implement technical solutions using Fuse’s internal tools, visual code workflows, and proprietary development platforms.

• API Integrations: Create and maintain integrations with REST APIs and external services.

• Cross-team Collaboration: Work closely with senior engineers, product managers, and tech leads to implement best practices.

• Provider Communication: Collaborate with external providers to ensure smooth integrations and resolve technical issues.

• Documentation: Maintain clear and well-structured technical documentation for components, integrations, and internal flows.

Essential Qualifications

• 4+ years of experience as a full-stack developer.

• Strong programming fundamentals (data structures, patterns, architecture).

• Hands-on experience building and implementing REST API integrations.

• Practical knowledge of JavaScript, modern frameworks (React), and backend technologies.

• Ability to work without a traditional IDE, using internal workflows and non-conventional tools.

• Experience building components, modules, or internal libraries.

• Strong ability to work independently and solve complex technical problems.

Desirable Traits

• Previous experience working with internal development tools or low-code/visual-code platforms.

• Familiarity with fintech or financial integrations.

• Experience in startups or high-velocity environments.

• Knowledge of Node.js, React, or similar ecosystems (not required if fundamentals are strong).

• Understanding of agile methodologies.
