About Us:
JobScore is an online network that privately matches people and jobs.
Over 1,000 employers use JobScore to manage their hiring. We process 1M+ job applications per year on their behalf.
JobScore is based in San Francisco, CA. We have some sports fans on our team.
We get fired up when we help our customers get better at hiring.
The Opportunity:
Lead front-end software engineering efforts for a team of a dozen full-stack engineers.
Make a big impact on a skilled and friendly Brazilian team.
Work on interesting problems. Write elegant code.
Occasionally travel to San Francisco, CA.
Balance your work-life and your life-life.
Work remotely. 100% of the team is Brazilian. Most of our team lives within driving distance of Joinville, SC, Brazil and we meet up there regularly in person if you’d like to join.
Responsibilities:
Take 100% ownership of how things look, work and perform on our web app front-end.
Research, evangelize and enforce coding patterns and standards, extending our React-based design system which is built on top of Material UI.
Review teammates’ code and inspire others to improve code quality and consistency.
Communicate with product to understand goals & vision. Negotiate which patterns to apply and chart a path to ensure goals are efficiently met.
Consult with designers and recommend existing, practical patterns when they get stuck.
Consult with other engineers to translate requirements, author plans & make accurate estimates.
Resolve differences of opinion through active listening and logic, not authority.
Lead projects to modernize existing (aging but bulletproof) code.
Learn and stay up to date. Share knowledge and make other engineers better, including testing and adopting new artificial intelligence-driven coding techniques.
Requirements:
7+ years of commercial software engineering experience, preferably working on a business productivity app with 250+ screens and/or a widely used consumer website (millions of visitors per year).
A love for UX patterns and structure. You’ve successfully set and evangelized standards in a 5+ person engineering team. It wasn’t easy, but everyone’s life was much better in the end.
You enjoy getting your hands dirty on the hard stuff. You’ve handled JavaScript nastiness more than you would like to admit. You eat cross-browser display issues for breakfast. You’ve been messing with DOM, JavaScript libraries, and frameworks for years.
You are well organized and a good communicator. You understand how to negotiate an end result, fill in the blanks, and drive it to done.
Perfect English comprehension (reading and listening). Functional written English (with some help from Grammarly).
Nice to Have:
Formal training in computer science
AI enthusiasm. You have experience investigating, learning, adopting, and teaching others to use AI in their day-to-day coding.
You love to teach. You’d prefer to teach someone else to fish and be awesome than do stuff yourself. You have references who refer to you as “one of the most important mentors I’ve had in my career.”
You are normally the best front-end developer when you join a team. You are no longer the best front-end developer when you depart that team.
Visual / Interaction Design experience. You’ve made mockups, and you enjoy doing so. Figma fluency is a plus.
3+ years of hands-on experience coding in React, Vue, or another JS framework.
Experience with Jest, Jasmine, Karma, or another front-end testing tool.
Knowledge of how web-based MVC frameworks work (like Rails, Django)
Rapid prototyping experience
Comfort using and extending a design system. You’ve authored style guides and coding guidelines, are happy to share them, and defend them after we read them.
Experience working in an environment focused on code quality and test-driven development (Unit, end-to-end testing, automation, etc.)
No fear when it comes to speaking English. A desire to improve your English communication skills. (unless, of course, you are a native speaker)
- Common Sense: You get that you’ll have no chance if you include a cover letter generated by an LLM, but a better shot if you write a great one from scratch.
