OnTheGoSystems: Data Analyst – AI Translation Quality
Company: Location: Remote Published: 2026-07-24
Headquarters: Remote
URL: http://onthegosystems.com
At OnTheGoSystems, we're building AI systems that help people translate content across many languages. Our LLM team works with AI-generated translations, user edits, customer feedback, and quality data to continuously improve translation quality.
We're looking for a Data Analyst who enjoys solving open-ended problems, finding patterns in complex datasets, and turning data into practical recommendations. This is not a reporting role. You'll decide what to measure, investigate why things happen, and help the team make better decisions based on evidence.
What you'll do
You'll own analytical problems from start to finish.
For example, you may discover that users edit translations much more often for one language pair than another. Instead of simply reporting it, you'll investigate why. You'll form hypotheses, gather the data, test possible explanations, and recommend the next steps.
Your work will include:
Defining meaningful metrics for translation quality, AI performance, and user behavior.
Monitoring trends and identifying unusual patterns or quality issues.
Turning observations into structured investigations and testing multiple hypotheses.
Extracting and combining data from SQL databases, NoSQL databases, logs, APIs, and CSV exports.
Comparing results across language pairs, AI models, providers, customers, content types, traffic levels, and other dimensions.
Separating real signals from coincidence by validating findings with data.
Reviewing translation samples to confirm whether patterns represent genuine quality issues.
Investigating root causes and recommending practical improvements.
Evaluating multilingual AI output for meaning, terminology, tone, formality, grammar, pronouns, and consistency.
Using AI tools, dictionaries, and other resources to investigate languages you don't speak, while recognizing when expert linguistic input is needed.
Reviewing AI-generated analyses, identifying incorrect conclusions, and helping improve our automated evaluation systems.
Building repeatable reports, scripts, and monitoring processes.
Communicating findings clearly to developers, product managers, and linguists.
What we're looking for
Strong analytical thinking, curiosity, and attention to detail.
The ability to work independently and define what should be investigated.
Experience turning open-ended questions into structured analyses and actionable recommendations.
A solid understanding of metrics, segmentation, distributions, correlations, and the difference between correlation and causation.
Experience writing SQL, Python, or similar scripts to collect, clean, and analyze data.
Experience working with multiple data sources, including databases, logs, APIs, and exported datasets.
Strong hands-on experience using AI tools while critically evaluating their output.
Fluent English plus at least one additional language (preferably European), with the ability to assess translation quality and explain language issues.
Clear written communication and the ability to explain analytical findings to non-technical colleagues.
Bonus points for experience with:
Translation quality or localization.
Multilingual content.
Data visualization or business intelligence tools.
Why join us?
You'll work on real AI systems used by customers around the world and directly influence how we measure and improve machine translation quality.
This role is ideal for someone who enjoys exploring difficult questions, testing ideas, and discovering insights that aren't immediately obvious. You'll have the freedom to propose your own analyses and the responsibility to turn them into evidence-based recommendations.
What we offer
100% remote position,
Body and Mind Movement program to fill you up with energy,
A computer budget to make your workplace better,
A Kindle device with access to our company Amazon account,
We respect national holidays in each country and want you to have a rest these days,
Great opportunity to progress and advance,
Collaborating with team members across the globe.
If you're excited by data, languages, AI, and solving complex problems, apply now, and we'd love to hear from you!

Yoko Co: Front-End WordPress Developer
Company: Location: Remote Published: 2026-07-24
Headquarters: McLean, VA
URL: https://www.yokoco.com/
We’re seeking a Front-End Developer who wants to make the world a better place through clean code, thoughtful craftsmanship, and a genuine love of building great websites.
This isn’t just about turning designs into code, it’s about translating ideas into experiences, solving problems along the way, and taking pride in the details that make a site feel right. This role is perfect for someone who enjoys the craft of front-end development, cares about doing things the right way, and is always looking for a better, more efficient way to build.
Why work at Yoko Co?
Do good, better: We exclusively serve clients who make a positive impact on the world. This is your chance to build things that help create a better place for all of us.
4-day flex week and lots of holidays. Mondays are flex days, meaning you’re free to take them off if you’re caught up on your work. Plus, we’re closed for nearly a full week at Thanksgiving (November), and two weeks at the end of the year, plus a bunch of other days, too.
High performance, no jerks. You’ll collaborate with good people who believe in doing great work. Best Place to Work (and that’s not just our opinion).
We’ve been named a Best Place to Work by the Inc. 5000 and Washington Business Journal. We value team members who are motivated by our mission and driven to make a positive impact.
If you have a passion for excellence, a growth mindset, and a commitment to collaboration, we’d love to hear from you.
What you’ll do:
As part of our development team, you’ll build websites and features from design references, turning Figma files into clean, maintainable, production-ready code. Our primary stack is built on Gutenberg block themes, so you’ll spend most of your time there, though you may also work on traditional WordPress themes and, occasionally, other page builders.
Build websites and site features from design references, using industry-standard code and best practices
Develop and maintain WordPress block themes using Gutenberg, templates, parts, patterns, and theme.json configuration
Work with traditional WordPress themes when needed, and occasionally with other page builder platforms
Write clean, well-structured HTML, CSS, and JavaScript
Build or extend front-end functionality using React or similar component-based approaches when the project calls for it
Use Git and GitHub for version control, following team branching and code review conventions
Work within a continuous deployment workflow, ensuring changes move smoothly and safely from development to production
Troubleshoot cross-browser and cross-device issues to ensure consistent, polished results
Collaborate with designers, project managers, and strategists to bring projects to life
Look for new and more efficient ways to deliver our work, whether that’s through better tooling, reusable components, or refined processes
Contribute to internal documentation, component libraries, and knowledge sharing
Stay current with WordPress, Gutenberg, and front-end development trends and best practices
What we’re looking for:
We’re less concerned with rigid checklists and more interested in capable, thoughtful developers who care about quality and enjoy solving problems. Strong candidates typically have:
Fluency in WordPress, with experience building both traditional themes and Gutenberg block themes
Comfort working with HTML, CSS, and JavaScript Experience translating design references (Figma or similar) into accurate, responsive, production-ready code
Familiarity with Git workflows and collaborative development practices
Experience working within a continuous deployment or CI/CD pipeline
Experience working with tools like Claude Code, Copilot, or Codex
An eye for detail and a commitment to clean, maintainable code Excellent written and verbal communication skills
Fluent English for written and spoken communication
Bonus points:
Experience building custom Gutenberg blocks
Experience with React or similar component-based frameworks
Experience working in a multi-client or agency environment
You may not want to apply if…
You prefer 100% concrete specs handed to you with no ambiguity and no changes. We do our best to provide final, locked designs and specs, but things inevitably change as a project progresses
You’re not interested in learning or working within Gutenberg block themes
You’d rather work solo than collaborate with designers, PMs, and strategists
You’re reluctant to incorporate AI into your workflow
Front-end development here is a mix of code and configuration, and often requires curiosity, flexibility, and a willingness to find the most efficient path to a great result.
What you get:
You’ll get a flexible schedule, unlimited time off, a competitive salary, a profit share bonus (starting in your second year), the ability to work wherever you want, a personal development budget, and all US federal holidays and multiple weeks off at the end of the year to recharge. We’ll also offset your entire carbon footprint. If you’re in the US, we also offer health insurance, disability and life insurance, and 401(k) matching.
More about us:
We’re a group of people who are passionate about the work we do, the clients we serve, and improving our craft. We also care about each other — we don’t think of one another as coworkers or employees, but as fellow humans. From developers to designers, project managers to strategists, we bring out the best in each other.
We’ve been in business for over a decade, our whole team is remote, and we’ve been named a Best Place to Work by the Inc. 5000 and the Washington Business Journal.
To apply:
If you’re interested, fill out our application form. An actual human from our team looks at every submission. As much as we’d like to, we can’t promise that we’ll reply to every application.
P.S. We encourage you to include a video message!
