Job Description

About LloydsDirect

NHS prescriptions are complicated. And we want to change that. Driven by an innovative spirit and strong moral compass, we’re on a mission to make NHS prescriptions simple for everyone.

Since 2015 we’ve grown from a plucky start-up to a team of over 200 people – and become the fastest growing pharmacy in the UK. Today, over half a million people use our apps to manage their NHS prescriptions, and our patients rate us as ‘Excellent’ on Trustpilot.

But there’s so much more to do. Because while 1 in 2 adults in the UK has a repeat prescription, only 3.2% of them use an online pharmacy. And we need bright minds to help us change how people manage their medicine for good.

True to our start-up roots, LloydsDirect has a supportive, entrepreneurial culture. We move fast, challenge the status quo, and always try to do the right thing. Sound good? Then we’d love to hear from you.

What you’ll do as Senior Software Engineer

As a senior engineer you will: - Understand our business goals and strategy and be able to make decisions based on them - Be able to take ambiguous problems, break them down, and help to find elegant solutions that don’t gloss over the details - Contribute to code shared across projects - Mentor other engineers through code reviews and pairing

This role is for you if

  • You’re excited by the idea of working on a product that helps make people’s lives better
  • The technology we use sounds interesting to you (or you already know and love it)
  • Reading a 1500 page document on the Zebra programming language sounds like a fun afternoon
  • You like being able to dip in and out of different parts of the stack wherever you are most needed and are keen to get stuck into and learn about the parts you don’t know yet
  • You love mentoring other engineers and believe that doing it is at least as valuable as your work as an individual contributor

This role may not be for you if

  • You’re more into quibbling about tech stacks or coding styles (we have linters for that) than creating a really great product
  • You measure your success by lines of code written over the impact it has
  • You only want to work off fully specified requirements and to not have to talk with your team mates

Perks & Benefits

● £350 per year physical wellbeing allowance e.g. gym membership, dancing classes ● £500 per year personal learning and development budget ● £500 per year working from home set up budget ● Enhanced maternity (13 weeks fully paid) and paternity (6 weeks fully paid) ● Pension contribution

Interview Process

  1. Screening call with internal talent partner
  2. 30 minute video call with head of engineering
  3. 45 minute video call to discuss ways of working
  4. 60 minute video call to assess technical skills

Senior Software Engineer
Luno
London, United Kingdom
ÂŁ80,000 to ÂŁ100,000 a year
October 2018
3 Applicants This Week
More Than 6 Months Old

Job Description

Luno is a leading global cryptocurrency company operating across more than 40 countries and with offices in London, Singapore and Cape Town. We’re a profitable, growing company with over 2 million customers, and are backed by some of the top tech investors in the world.

Our products and services make it safe and easy for people and businesses to buy, store and learn about cryptocurrencies like Bitcoin and Ethereum. Our vision is to upgrade the world to a better financial system.

To the moon! 🚀

Your Mission

We have multiple openings for senior software engineers in our brand new London office. These are in a range of teams including fraud, platform, payments, shield, onboarding, and crypto-security. With over 40 engineers based in our Cape Town office, you’ll be joining a group of highly motivated experienced developers who you’ll work collaboratively with across our currency exchange, fraud, payments and compliance pods.

As a small company operating on a global scale, you’ll immediately see how your contributions directly impact both our internal users and client experience. We make decisions based on facts, not fiction. Many of the problems we’re solving result in genuinely trail blazing solutions which can’t be found on StackOverflow; so we’re looking for an experienced engineer that thrives on working in a complex domain.

We use Go, microservices architecture (gRPC) and AWS, but if you come from a Java, Python or other relevant language we’ll help you get up to speed with our comprehensive engineering onboarding program.

How we work

We succeed as a team. Our teams are split into pods, each of which focuses on a specific aspect of our product. Any engineer is able to deploy to production, and we deploy multiple times each day. Your pod will include a product owner, back end engineers, Android and iOS developers, and web developers who each bring a unique perspective to the problem you’re all solving.

A typical day

  • Join the pod’s daily standup to share progress and remove blockers
  • Collaborate with other engineers on the design of a new payment integration to launch to a new market
  • Write clean, well-tested code that directly affects users, the company and the Bitcoin ecosystem
  • Grab lunch with the company (we provide lunch Monday - Thursday)
  • Coach a team member by giving feedback on their pull-request

What’s in it for you

This is a fantastic opportunity to learn more about cryptocurrencies, blockchain, emerging and developed markets, and scaling a global business. We provide great benefits and the autonomy to conceive and execute your own projects. Best of all you get to work with a diverse team of talented, ambitious and friendly people on something that will truly revolutionise the world.

As a “Newnaut” we’ll fly you to Cape Town to meet the wider team, and go through our comprehensive onboarding program. We expect you to have a passion for blockchain and cryptocurrencies but we understand that this is a new industry so we’ll help you learn about how the blockchain works and understand all aspects of our business.

What you’ll need

Building a new financial system for the world requires a special breed of people working together with unusual skill, focus and determination. “Moontality” represents the ten core principles that underpin everything we do, setting us apart from the rest.

As an experienced lead-level or senior engineer, you’ll have:

  • A solid foundation in computer science in areas such as algorithms, data structures, and software design
  • Extensive programming experience in an object-oriented language. We use Go but we welcome applicants who have strong experience in other languages like Java, Scala or C++, etc.
  • Proven experience of building, shipping and supporting a product
  • An interest in cryptocurrencies like Bitcoin

Don’t be put off if you don’t tick all of the boxes – they’re a guide based on what we’d love to see but we appreciate that great software engineers have diverse backgrounds.
