Full Job Description

About Orbweaver

Orbweaver is a supply chain software and integration platform that helps manufacturers, distributors, suppliers, and procurement organizations modernize complex commerce and operational workflows. Through configurable SaaS products, APIs, EDI connectivity, integrations, and data orchestration capabilities, Orbweaver enables customers to automate critical business processes, improve visibility across systems, and streamline collaboration throughout the supply chain ecosystem.Our customers operate in aerospace, medical, defense, and industrial electronics, where part data has to be governed, versioned, and traceable. The interfaces we build carry real operational weight: a procurement lead approving a bill of materials, an engineer resolving a lifecycle conflict, an integration analyst tracing a failed document exchange. At massive scale, precision becomes a competitive advantage, and the interface is where that precision either holds or breaks down.

About the Role

Orbweaver is looking for a Mid-Level Frontend Developer with 5–7 years of hands-on experience to join our engineering team. This role is for someone who has moved well past the fundamentals: you've built and shipped real products, you understand why the code works the way it does (not just how to make it run), and you're genuinely curious about the systems and tools you use every day. You'll be trusted to take a feature from a rough idea through UI/UX design and workflow thinking all the way to a shipped, production-ready implementation.

What You'll Do

Design and build user interfaces and workflows from concept to completion, translating product requirements or rough ideas into clean, usable, and maintainable experiences.
Develop and maintain front-end applications using modern JavaScript frameworks (React, Svelte, Angular, or Vue).
Implement responsive, consistent UI using CSS frameworks such as Tailwind or Bootstrap, while knowing when to write custom CSS instead of reaching for a utility class.
Collaborate with design, product, and backend engineers to turn requirements into technical plans, then execute on them independently.
Write clean, well-tested, maintainable code and participate actively in code review — both giving and receiving feedback.
Debug and troubleshoot issues across the stack, digging into root causes rather than patching symptoms.
Continuously evaluate and suggest improvements to our front-end architecture, tooling, and development practices.

What We're Looking For

5–7 years of professional experience building and shipping web applications.
Deep, practical experience with at least one modern front-end framework (React, Svelte, Angular, or Vue) — comfortable discussing trade-offs between them, not just syntax in one.
Strong experience with a CSS framework (Tailwind, Bootstrap, or similar), along with solid fundamentals in CSS/SCSS so you're not dependent on the framework to get things right.
Experience with testing frameworks (Jest, Cypress, Playwright, or similar).
Experience consuming and integrating data from REST or GraphQL APIs, including handling authentication, pagination, error states, and loading/caching patterns on the front end.
Demonstrated ability to design a UI and workflow, not just implement one handed to you — comfort with wireframing, UX thinking, or working closely with designers to shape the solution.
A genuine curiosity about how things work under the hood — browsers, build tools, frameworks, the network — and a track record of digging in rather than stopping at "it works."
Solid understanding of JavaScript/TypeScript fundamentals, asynchronous programming, and browser behavior.
Experience with version control (Git) and collaborative development workflows.
Strong communication skills and the ability to work independently on ambiguous problems.

We're specifically looking for candidates whose skills go beyond bootcamp-level fundamentals — real production experience, judgment born from shipping and maintaining code over time, and the ability to reason about a problem rather than pattern-match a tutorial.

Nice to Have

Familiarity with component libraries, design systems, or accessibility (a11y) best practices.
Exposure to performance optimization and web vitals.

Pay: $90,000.00 - $120,000.00 per year

Benefits:

401(k) matching
Dental insurance
Flexible schedule
Health insurance
Paid time off
Parental leave
Retirement plan

Bethlehem, PA 18018 (Preferred)
