React Native Jobs - January 2019

If you have a soft spot for bootstrapped, profitable companies with a meaningful product, and you want to use your frontend development skills for good, you’ll like this.

About us:

Drops’ goal is to turn language learning into a delightful game while ensuring effective learning. We teach 31 languages, was featured by both the App Store and Play Store multiple times - and received the “Best of 2018” title this year! - and the company is still run by the founders. We are a small, super-capable remote team mainly spread across Europe. We’re working synchronously, so time zones matter for us. We communicate via Slack, Github and have releases multiple times a week. We want to be the #1 app for vocabulary learning and we are getting there quickly with our current user base of 9 million, a monthly active of >1,000,000 and an average store rating of 4.7. You can find us here: https://languagedrops.com

About you:

You’ll be responsible for establishing Drops on the web, from a technical perspective. This means a lot of ownership, which we cultivate by having a flat structure.

You’re a no-nonsense person, who is comfortable taking on and managing multiple different projects at the same time, who has been working in working at a product company and has extensive front-end development experience.

You have been working with React for years, have deep knowledge of everything that’s happening in the browser and looking for challenges in growing a product from tens of thousands to millions of visitors per month.

You strongly prefer static typing over dynamic languages, and use every opportunity to transform code that doesn’t use types into code that does. You generally prefer to use a minimal set of simple tools to a diverse range of complex ones.

We’ve built our mobile app with react-native, so we can easily port it to the web and start sharing most of our code - and the challenges that this brings are of your interest.

You like to have a variety of projects - at this job, you’ll be developing a complex web app, a static site generator (gatsby), and even sometimes helping out on our marketing website, that’s being re-built with webflow.

We want everyone to see the big picture: this means you already pushed your boundaries outside of “being a developer” and are knowledgeable about web product growth frameworks, SEO, best practices regarding retention and monetization.

We’re building a small, but super capable team. You’re naturally more interested in the fate of the product & driven to grow professionally, than in managing people.

We value clear and honest communication and transparency, it’s the linchpin of our culture and current success and freedom. You will be involved in both high and low level decision making and will be available during European working hours (9AM - 6PM GMT).

We are looking for a missionary rather than a mercenary.

Hinge Health | San Francisco | ONSITE | Senior Mobile UI Engineer

We've got an exciting opportunity available for someone who's been itching to work on a production-grade React Native mobile application. This job is for you if:

- you think TypeScript is a leap forward and can't wait to use it in a professional context (no prior experience necessary!).

- React makes you look back on imperative UI programming as the "dark ages".

- despite all the above, you'd feel 100% comfortable writing a light web app in Vanilla JS.

- you love the idea of directly helping people, rather than mining them for data.

- compromising on user experience, letting users do the QA work, or other similar abuses of users' trust does not fly in your book.

This is not at all an entry level position, and our standard for a Senior Engineer title may be higher than what many people are used to. We'll be particularly looking for a track record of building user interfaces in a professional context – code samples and live demos are a big plus.

Email me directly with "Hello from HN" in the subject line to hear more about the position and to apply formally.

Thanx | SF, DEN, Remote | Principal Engineer | ONSITE/REMOTE, Full-time | $160-$200K | https://boards.greenhouse.io/thanx/jobs/903207

Americans spend more than $5 trillion on restaurants, retail, and services each year. Nearly 90% of those transactions happen in a real-world store. Data is king and online it powers personalized customer experiences and product recommendations. Offline, however, it’s still 1999. Brands are blind to their customers, causing them to spend more and more money on “megaphone” marketing. No wonder brick-and-mortar stores are being left behind.

Thanx is fundamentally changing that. Thanx personalizes every interaction between a merchant and their best customers, resulting in measurable increases in revenue for merchants and far greater personalization for consumers. How? • Through proprietary partnerships with credit card networks (e.g. Visa, Mastercard, Amex), Thanx can reward consumers for their purchases and deliver highly-customized promotions • Through our interactive dashboard, Thanx makes even the smallest marketing team a data-science driven expert in personalization - right message to the right customer at the right time through the right channel. • By measuring our success based on revenue generated (not opens and clicks of emails)

Think of us as Salesforce meets Google Adwords for offline retail. Thanx is backed by some of the best investors in the world — Sequoia Capital, Icon Ventures, and Andy Rachleff (CEO Wealthfront, cofounder Benchmark Capital).

Thanx Engineering • Team: early engineers at AWS, Cloudera, Climate, Zenefits, Okta. Experience from successful product companies like Disney, Google, and Facebook. This is an elite engineering team, period. • Growth: 10x YOY data growth; $100M+ delivered to merchants; 200% team growth; modern, rapidly-evolving platform -- adopted Golang, Elasticsearch, NLP, React, React Native, GraphQL, and added 5+ new microservices; all in the last 12 months. And we are just getting started. • Culture: data-driven decision-making, risk-taking, no hierarchy, collaboration & shared responsibility, testing and continuous improvement. As a remote-friendly team, we have flexible work hours and PTO policy. We work and play hard -- be warned, when it comes to Mario Kart, we are super competitive!
