JOB DESCRIPTION
We are seeking a highly skilled Staff JavaScript Developer to design, build, and optimize our Web SDK. This SDK will be at the core of our solutions for device fingerprinting, identity verification, and behavior analytics, enabling our customers to stay ahead in the ever-evolving fraud prevention landscape. This is not a UI or App development role, this is building SDKs for detecting fraud by analyzing device and behavioral properties. This requires deep understanding of the platform internals. As a Staff Developer, you will lead the design, development, and performance optimization of our Web SDK, leveraging your deep expertise in JavaScript, TypeScript, and modern web technologies. You will collaborate across teams to deliver a secure, scalable, and developer-friendly SDK.
Responsibilities
- Lead the development and maintenance of a high-performance Web SDK for collecting and analyzing browser and device-related data.
- Design and implement algorithms to create unique device fingerprints and capture behavior-based insights (e.g., gestures, keyboard, and mouse interactions).
- Build and maintain a robust CI/CD pipeline with automated cross-browser testing and release cycles.
- Continuously optimize SDK performance to minimize resource usage and ensure a seamless user experience.
- Stay updated on emerging web technologies, security practices, and industry trends to enhance SDK capabilities.
- Develop clean, maintainable, and well-documented code aligned with the best coding practices.
- Conduct thorough code reviews and mentor junior engineers on best practices.
- Collaborate with cross-functional teams—including product managers, designers, and QA engineers—to meet high-quality standards and customer requirements.
- Ensure data privacy and security principles are embedded in the SDK’s design and implementation.
- Drive innovation in browser-based solutions for risk, fraud detection, and device analytics.
Technical Skills
- Proficiency: JavaScript (ES6+), TypeScript, REST APIs, Git, and version control tools.
- Web SDK Expertise: Extensive experience designing and maintaining Web SDKs or libraries with a focus on data collection, tracking, or analytics.
- Browser APIs: Deep understanding of browser environments, APIs, and efficient handling of browser-related data.
- Security Principles: Strong knowledge of data privacy, encryption, hashing, and obfuscation techniques.
- Cross-browser Compatibility: Experience in building solutions that work seamlessly across various browsers and devices.
- Server-side Familiarity: Understanding of server-side technologies and RESTful APIs for data retrieval and storage.
- Build Tools: Proficiency in modern build tools and frameworks like Webpack, Babel, or Rollup.
Soft Skills
- Excellent problem-solving abilities, with attention to detail and a focus on delivering high-quality solutions.
- Strong communication and collaboration skills to work effectively in cross-functional teams.
- Ability to mentor and provide constructive feedback to junior developers.
Education & Experience
- Bachelor’s degree in computer science, Software Engineering, or a related field (or equivalent experience).
- 8+ years of experience in web development, with at least 3 years focused on building and maintaining SDKs.
- Proven track record of contributing to open-source projects or showcasing relevant work on platforms like GitHub.
PREFERRED QUALIFICATIONS
- Experience with AI-driven analytics, risk systems, or fraud prevention technologies.
- Familiarity with JavaScript SDKs, gestures, and interaction data processing.
- Prior experience in a high-scale, distributed environment.
BENEFITS
- Compensation: Competitive salary and equity packages, including a 401k
- Flexibility: Remote-first culture — work from anywhere
- Health: 100% Employer covered comprehensive health, dental, and vision insurance with a top tier plan for you and your dependents (US)
- Balance: Unlimited PTO policy
- Technical: AI First company; both Co-Founders are engineers at heart; and over 50% of the company is Engineering and Product
- Culture: Family-Friendly environment; Regular team events and offsites
- Development: Unparalleled learning and professional development opportunities
- Impact: Making the internet safer by protecting online transactions
If you are passionate about creating impactful web SDKs and enjoy solving complex challenges in risk and fraud prevention, we’d love to hear from you.

Tips for Your Javascript Developer Job Search
Tailor your resume to the stack
List the frameworks and libraries you've shipped production code in, not just ones you've touched. Hiring managers for javascript developer roles scan for React, Next.js, or Node.js before reading anything else, so put those at the top of your skills section.
Show your work with live links
Attach a GitHub profile or deployed project URL to every application. Interviewers for javascript developer roles will open your code before your interview, so make sure your repositories are clean, documented, and show components or APIs you built end to end.
Filter openings by your preferred runtime
Many javascript developer postings are front-end only, back-end only, or full-stack. Narrowing by keyword terms like 'Node.js' or 'React' cuts irrelevant listings fast and puts you in front of teams that need your exact skill set.
Apply early to roles that fit
Migrate Mate lists javascript developer openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Prepare for a live coding assessment
Most javascript developer interviews include a timed coding exercise on platforms that test DOM manipulation, async patterns, or algorithm problems in vanilla JS. Practicing those without a framework keeps you sharp for the lowest-common-denominator rounds.
Negotiate using your deployment history
When discussing compensation, anchor on the scale and complexity of what you've shipped, not just your years of experience. Teams hiring javascript developers respond well to specifics like traffic handled, bundle size reduced, or latency improvements you directly caused.
Javascript Developer Jobs: Frequently Asked Questions
Which companies are hiring the most javascript developers?
The companies hiring the most javascript developers right now include Artech, Gallega Software Solutions, and IntePros, with the largest share of openings in Massachusetts, California, and Georgia, based on current listings on Migrate Mate as of June 2026. Demand is concentrated in product-led companies and consultancies scaling their web platforms.
How many javascript developer jobs are remote?
About 11% of javascript developer openings are fully remote or hybrid as of June 2026, making it one of the more location-flexible engineering roles available. Front-end and full-stack positions tend to carry the highest remote share, while on-site requirements appear more often in regulated industries like finance and healthcare.
How do you become a javascript developer?
Start by mastering core JavaScript fundamentals including scope, closures, asynchronous patterns, and the event loop before layering on a framework. Build several projects you can deploy publicly, document your code clearly, and contribute to open source to show real collaboration. Most developers land their first role after assembling a portfolio of three to five shipped projects that demonstrate end-to-end ownership.
Can you get hired as a javascript developer without a degree?
Yes, many employers hire javascript developers based on portfolio work and demonstrated skills rather than a formal degree. A strong GitHub profile with deployed projects, experience with modern frameworks, and the ability to pass a technical screen matter more to most hiring teams than your educational background. Bootcamp graduates and self-taught developers regularly compete for the same roles as four-year degree holders.
What does the javascript developer interview process look like?
Most javascript developer interview processes start with a recruiter call to confirm your background and role fit, followed by a technical phone screen covering JavaScript fundamentals. Next comes a take-home or live coding exercise, often in a framework like React, and then a system design or architecture conversation for mid-level and senior candidates. Final rounds typically include a team interview focused on collaboration and past project decisions.
Where can I find and apply to javascript developer jobs?
You can find and apply to javascript developer jobs on Migrate Mate, which lists current openings from across the United States in one place. Search the listings for roles that match your stack and experience level, then apply directly to each one that fits.
