Job Description

Permutive is looking for a Software Engineer to help connect our real-time data management platform to the rest of the world.

Our JavaScript runs on millions of devices every day, and as a core part of the Permutive platform it is essential that it is an efficient, performant and maintainable codebase. We are looking for an engineer to take full ownership of our JavaScript SDK - maintaining the roadmap, planning new features and seeing them through to deployment.

An ideal fit would be a recent graduate with a Computer Science background, who perhaps plans to be a co-founder and wants to get a deeper understanding of early stage startups. Or you'll be a more experienced engineer with some JavaScript experience, who is keen to join a growing engineering team and make a real difference. Either way you'll be excited by the opportunity to join a fast-growing start-up, in a role where you'll be able to take ownership of a core part of the platform.

*Who We Are*

We’re a small team trying to make big data actionable by anyone. We believe that enterprise companies build clunky platforms which make big data confusing, frustrating and boring. Manipulating billions of data points should feel like you’re being plugged into the Matrix; not into a 90s accountancy package.

Our technology is fundamentally different. Every day we process billions of events across hundreds of millions of users - and we give results in milliseconds. We’ve built the world’s fastest Data Management Platform and the implications are huge.

Revenue is growing super fast; we’re working with flagship publishers and marketers; and we’re beating billion dollar competitors in market. On route to this, we’ve been backed by some of the world’s best investors, including Y Combinator, EF and Octopus Ventures.

Behind the scenes our goal is to build an incredible company with an extraordinary culture. We’re looking for people who are excited by growth, embrace responsibility and are excited by enormous challenges. It’s a really exciting time to join, experience start-up life and shape who we become.

*Key Responsibilities*

On a day-to-day basis you will:
* Maintain a roadmap for the JavaScript SDK and plan new features
* Manage deployment of our JavaScript tag when putting new customers live
• Debug and resolve JavaScript tag issues, and work closely with customers to fix errors
• Write custom JavaScript code to enable clients to send custom data into Permutive
• Communicate with both customers and partners, to spec out and build client-side JavaScript integrations
* Find ways to optimise code, to ensure it is clean and performant
* Build an automated test framework for our JavaScript SDK

As an early hire you will also have the opportunity to be exposed and contribute to every aspect of the business, from product decisions and development processes to strategy.


We think to be brilliant in your role you really need to have:
• A degree in Computer Science or a related discipline, or the equivalent in work experience
• Ability to write performant client-side JavaScript code
• Knowledge of jQuery, AJAX, cookies, browser storage, HTML and CSS
• Ability to efficiently debug code using Chrome’s DevTools
• Have a broad understanding of software engineering concepts
• Excellent verbal and written communication skills

It would be a plus if you have any of these:
* Knowledge of TypeScript
• Experience with more advanced JavaScript concepts like modules, futures and websockets
• Experience writing an SDK to enable interaction with a product, service or API
• Experience with JavaScript testing frameworks, such as Zombie.js
• Experience with JavaScript build frameworks, such as Grunt
• Experience writing server-side JavaScript with Node.js
* Experience in a client-facing or technical support role


In our mind the real benefit is to join a team where you have a laugh together, have a huge personal impact on decisions and get excited about things together. It’s that incredible team feeling of ‘You’re my team and we’re gonna smash this’.

As a VC backed start-up we hope you’ll gain a huge amount from working with our team.

And, of course, there’s other perks too.
• Stock options, so you get to own a piece of the pie
• Weekly lunches and quarterly socials. Highlights recently included Mexican food, escape room and pub trips
• So many office snacks you’ll never go hungry or thirsty
• Offices just off Brick Lane
• A Macbook
