Intro

EAGLE Power Holdings aims to launch a portfolio of new energy retail brands, all of which enjoy the efficiency of a single technology platform. We want to do more than offer cheap "green" tariffs, and believe that our range of engaging brands can identify with shifts in consumer preferences (e.g. growth of EV usage), with the value of local communities, and with proactive support of broader ESG causes.

Our long-term strategy is technology-driven, and involves unlocking value through the digitalisation of processes around customer acquisition, engagement, and retention.

Developers at EAGLE flourish in an agile process where collaboration and ego-free communication is valued. We believe in developing working software throughout the entire product development process. We engage in product thinking as a team, and cross-functionality among product managers, designers, and domain experts is promoted.

How you fit in

Engineering is the executional function of EAGLE's software delivery wing. As a Senior Frontend Developer, you are expected to take control of complex B2C projects being built from scratch. Moreover, not only are you expected to write clean, tested, and maintainable code but you will also be a central part of a product team that iterates constantly, ships regularly, and learns continuously. You will have the creative freedom for learning, experimenting, and responsible risk-taking in a startup environment.

What your role consists of:

• Collaborate with engineers, UI/UX designers, and product owners to build & ship new features and maintain/enhance existing ones
• Design & develop engaging front-end and user interface solutions to address complex and valuable business problems
• Implement best practices of test-driven development, automated deployment, refactoring and code standards
• Tackle complex problems, consider multiple solutions, and determine the best course of action
• Assist with the API design, development, and documentation of our UI kit
• Debug production issues across services and multiple levels of the stack

• Help inform product prioritisation and scoping decisions by evaluating technical complexity and risk

• Improve engineering standards, tooling, and processes

• Maintain technical documentation

What you bring to this role:

• 3+ years experience working with JavaScript, HTML, CSS & React in a distributed, collaborative, agile environment while delivering solutions on a regular cadence
• An ownership mindset: you should look not only at what you’re asked to do, but ask why you’re doing it and how it impacts on the rest of the product, our customers, and whether it makes sense
• A deep understanding of React and an eye towards writing efficient, performant, and tested code
• Experience in core aspects of web application development, including design, development, performance, integration, analytics, usability, and accessibility
• Experience developing applications from the ground up
• Proven ability with interaction/UI design
• Excellent communication skills and ability to give and receive constructive feedback
• Passion for the whole product process. You will have your specific areas of focus, but we find those that are passionate about the bigger picture collaborate best with cross-functional teams
  
  

Nice to have

• Portfolio showcasing previous work with interaction/UI design

Where we are

While the company is registered in the UK, the software delivery wing is being built to be remote-first. Whether you prefer to be in situ or a digital nomad (or anything in between), you are welcome.

What’s in it for you

We offer competitive salaries based on prevailing rates in your local employment market, but there is further room to negotiate if you are the right candidate.
In addition to your basic package, you can expect to receive the following benefits:

• Flexible working hours
• Unlimited annual leave
• On-the-job coaching, and access to mentorship by industry and domain thought leaders
• Full or partial sponsorship for professional/skill development courses, certifications, and other learning opportunities (evaluated on a case-by-case basis)

About EAGLE Power Holdings

In a nutshell: Transforming energy retail and supply through cutting-edge software and AI technology

The venture is in ‘stealth mode’ as we lay the foundations for blast-off. It has been launched by a team with a history of entrepreneurial successes. These include one in the climate change space which services the Californian and North America carbon markets, and another which provides highly refined machine learning software to the energy arena in Asia. Both companies were acquired last year. 

This start-up was launched in London at the end of 2020, and will focus on the deregulated energy market in GB. The mission is to discover, or invent, a viable business and operational model for energy retail within the near-zero-cost energy ecosystem that the world is moving towards. This transformation is driven by the ever-decreasing prices of renewables and alternative generation, and by the exponentially growing volumes of national energy system data. We believe these factors have yet to truly disrupt the market, and intend to accelerate the sharing of value back to consumers.
