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 server-side developer at Eagle, you will drive complex projects being built from scratch, and lead the junior members of the team. Not only are you expected to write clean, tested, and maintainable code, 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 software solutions while ensuring the solution is scalable and can handle large data, complex analytics, and multi-tenancy
- 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
- Debug production issues across services and multiple levels of the stack
- Help inform product prioritisation and scoping decisions by evaluating technical complexity and risk
- Work on internal tooling to improve the development experience of other engineers and ship faster and safer
- Provide junior engineers with feedback regarding application engineering methodologies, standards, and leading practices when appropriate
What you bring to this role:
- 4+ years of significant experience building scalable web applications 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
- Extensive experience with distributed service architecture
- Extensive experience with modern NoSQL technologies
- Extensive experience in cloud automation & test-driven development
- Excellent communication skills and ability to give and receive constructive feedback
- Ability to to mentor or coach less experienced engineers
- 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 haves:
- Experience with Golang
- Experience with Serverless infrastructure
- Experience with multi-tenant system designing
- Experience with building & integrating CI/CD pipelines
Where we are
While the company is registered in the UK, the software delivery wing is built to be remote-first. Whether you prefer to be in situ or a digital nomad (or anything in between), you are welcome. We are not inclined to support relocation to London for candidates that are not already based there, as we are a remote-first company.
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)
- Monthly allowance package for remote working (coworking membership or cash allowance)
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/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.
Responsibilities Include
You will break down business opportunities and problems into software solutions. You will work closely with the CTO to help product and marketing stakeholders distill the product vision and roadmap, into a technology vision. You will be responsible for the evolution of an already bleeding-edge highly distributed systems at the back-end, and would need to work with front-end architects to come up with the best user experience for the gaming platform. You will be required to make decisions quickly, and work under strict timelines. You would lead technology strategy through analysis of market trends and product requirements. You would help set coding guidelines and help bring the most modern tools to keep engineering processes most efficient.
Requirements
- B.E/MS in Computer Science or equivalent.
- 10+ years or more of progressive software technology experience with at least 3 years in an architectural role.
- Completely hands on with technology and architecture. Start-up experience is a huge plus.
- Ability to quickly prototype and demonstrate technology value adds and educate + drive adoption within the extended technology team
- Excellent and robust understanding of scalable product system architecture(s), platforms and core technologies
- Demonstrated problem-solving and leadership skills to pursue correct engineering process in adverse conditions. Ability to embrace and demonstrate leadership beyond ownership
- Work with engineering leadership to setup and manage processes.
- Track record of thought leadership and out of the box thinking in the technology arena.
- Ability to work efficiently in an entrepreneurial and in a start-up environment
- A Java/Spring/Akka, Javascript or Golang rockstar.
- Deep and hands on knowledge of some of these technologies - MySQL, NodeJS, message brokers such as Kafka/RabbitMQ, NoSQL datastore such as Mongo, Cassandra, Arango, distributed caches such as Redis/memcached, container technology such as Docker and Kubernetes etc.
- Great proficiency in distributed systems design, with an ability to make the right trade-offs for creating future-proof solutions.
- Building quick PoCs and full-fledged solutions with various AWS managed services would be a big plus.
