Octopus Energy

Lead Mobile Engineer

Remote London, UK
Kotlin Android
Description
We’re a leading energy technology (EnTech) company, providing a better experience for our customers through transparency, honesty and simplicity. Better for the planet, through real long-term investment in renewable generation and a low CO2 future.

We're on a mission to make energy greener, fairer, and genuinely better for people. Our global energy revolution is backed by Generation, the sustainable fund co-chaired by Al Gore. To succeed with this mission, we need excellent technical people who want to use their skills on the biggest challenge the planet is facing.

We’re proud to be Europe's best-funded green tech start-up, and one of Glassdoor's Best Places to Work. We’re also the most awarded energy supplier in the UK, and have been Which? Recommended eight years in a row.

Mobile at Octopus Energy
The mobile team within Octopus Energy Engineering is responsible for the mobile app that connects over three million monthly active customers across eight countries to the energy solutions that shape their daily lives. From seamless onboarding and smart control of cutting-edge Octopus Energy hardware, to loyalty schemes and demand flexibility, our work is at the heart of the clean energy revolution.

We’re growing fast to meet the demands of a global business with a single app, and we’re looking for passionate engineers who want to build technology that makes a real impact. If you want to shape the future of energy tech, solve complex problems, and build products that genuinely help people, we’d love to hear from you.

Our Team
We relaunched the Octopus Energy app with a small team of 4 engineers, product, and design in 2021. Since then we’ve grown to multiple cross-functional teams and 20+ mobile engineers. We’re expanding to meet the challenges of rolling out a single platform which supports diverse utility markets around the world. Every team member helps define culture and processes necessary to work collaboratively and effectively across multiple product teams, whilst instilling good engineering practices for the team as a whole.

Our Technology
As an organisation we like to move quickly. This is true both in how we operate as a business and the technology choices we make. We were very early adopters of Kotlin Multiplatform (KMP) and used the technology when it was in pre-alpha, at scale, to great success. It helps us share code across Android and iOS without the user experience tradeoffs.

KMP was officially released in late 2023 so we don’t expect our applicants to have experience using it. It powers the extensive shared layer across our Android and iOS apps, with UI powered by Jetpack Compose and SwiftUI. Our app is built around offline-first reactive patterns and utilises unidirectional data flow with a layered architecture. Our view models are written using Jetpack Compose and compliment our state driven UI.

We release updates to customers weekly. We gain release confidence with our suite of automation and unit tests running in CI (GitHub Actions), and configure features remotely using feature flags.

What you’ll do
You’ll be involved in the Devices team efforts to scale our app to meet the needs of current and future Octopus Hardware. This is a hybrid role of management and engineering, you’ll be responsible for 4-6 engineers and work closely with them to guide technical direction, coordinating with the teams that design and build the hardware, silicon and firmware that powers Octopus products like the Cosy heat pump and Octopus Home mini.

We embrace flat hierarchies and an open, agile culture that fosters innovation, flexibility, and creativity. 

We don’t hang our personalities up with our coats and nor should you. At Octopus, we hire great people who get stuff done, all whilst being themselves.

  • You’ll be someone who appreciates the impact a nimble team can make on customers and clean energy.
  • Your passion for clean energy and sustainability will help provide context on your everyday work.

I've been using this job search site for a while now, and it’s honestly one of the best out there! The clean and easy-to-navigate UI makes the whole job-hunting process so much smoother. Plus, the job postings are always up-to-date, so I never feel like I’m wasting time. The cherry on top is the owner—super kind and always quick to respond. Definitely recommend checking it out if you're on the job hunt!

What I like most about Echo Jobs is how easy it is to use. The platform helps me quickly find jobs that match my skills and interests, thanks to its great recommendations and filters. Yes, I would definitely recommend Echo Jobs to a friend. It makes job searching simple and efficient, making it a great tool for anyone looking for a new job.

As a student navigating the job market, I've found LinkedIn increasingly frustrating due to numerous fake postings by consultancies. In contrast, this job posting website has been a game-changer for me. It offers genuine opportunities and a straightforward application process, making it much easier to find and apply for real jobs. Highly recommend it to fellow students seeking reliable job listings!

Echo Jobs has been exceptional in my job hunt where it provides one platform to job hunt and I don't have to open 10 websites just to look for a job. It has also helped me focus much on the job skill and the location filtering out the onsite jobs and remote ones. The only feature that I would request is to display fully remote jobs that are not restricted to a country since the one available shows ie, Remote, US yet. But if it could show remote only, that would be helpful not only to me but to other people applying for full remote and not tied to only US candidates

I found EchoJobs in 2022, and I love it. It has a lot of remote jobs. It's exclusive to software and technology jobs (helpful for devs like me). What I like the most are its filters and its API. If you're a tech professional seeking remote work, I highly recommend giving it a try to EchoJobs.

Best wishes with EchoJobs—it's become my favorite job board overnight!
Dec 16, 2023
Simply put, it's the most up to date tech jobs aggregator I’ve found. I'm like... "I don't have to check 10+ jobs boards daily just to see if there's a new job listing? sign me up!" The filters are also quite helpful! The UI is very clean and straightforward. Love it!
