We’re building a modern, data-driven technology platform from the ground up and are looking for a Senior Front End Software Engineer who wants real ownership , real impact , and the chance to shape a product, not just tickets. This role is based in Dallas, TX , working alongside a small, driven team tackling complex problems with clean, scalable solutions.

You’ll be hands-on building intuitive, high-performance interfaces using JavaScript, TypeScript, and React, with meaningful influence over frontend architecture and user experience. Experience in Fintech, Financial Services, or Real Assets (Oil & Gas, Real Estate, etc.) is a plus, but curiosity and execution matter more than domain pedigree.

Key Responsibilities

• Build and evolve production-grade frontend applications using JavaScript, TypeScript, and React.


• Own frontend features end-to-end—from early design discussions to production release.


• Partner closely with backend engineers and UX/UI designers to deliver fast, intuitive, and reliable user experiences.


• Turn product ideas and wireframes into elegant, maintainable code that scales.


• Integrate frontend applications with APIs, services, and data pipelines.


• Influence frontend architecture, tooling, and best practices as the platform grows.


• Stay on top of modern frontend trends and introduce improvements that actually move the needle.


• Experience with geospatial data, spatial modeling, or data visualization is a strong plus.

Qualifications

• 5+ years of experience building modern frontend applications.


• Deep hands-on experience with JavaScript, TypeScript, and React.


• Strong product mindset—you care about why you’re building something, not just how .


• Comfortable operating in ambiguity and moving fast without sacrificing quality.


• Sharp problem-solving skills and a bias toward action.


• High standards for performance, usability, and clean code.


• Collaborative, low-ego teammate who communicates clearly with both technical and non-technical partners.


• Strong sense of ownership, accountability, and ethical responsibility.
