Senior Software Engineer in Nottingham

We're building the digital infrastructure that makes clean energy work in the real world. Seventy million machines run on diesel. The alternatives exist. But the operations are complex, the supply chains are still emerging, and for most companies the transition feels risky. That's the problem we're solving. Logiq Systems builds the operational intelligence layer that makes clean energy work in the real world. One platform for fuel suppliers, rental companies, and asset operators to deploy, monitor, and optimise hydrogen, battery, solar, and alternative fuel systems — at the scale and reliability that industries actually need. We're live across construction, events, and industrial sectors with customers including Toyota, Balfour Beatty, Acciona, Sunbelt Rentals, and Protium. The technology works. Now we're scaling the team that scales the business. If you want to work on infrastructure that matters, in a company early enough that what you do shapes the industry, we'd like to hear from you.

Role Summary: We are looking for a Senior Software Engineer (full-stack) to develop the Logiq platform. Working closely with our Head of Product, you will be responsible for building software that forms the core of our main business, as well as defining the long-term technical direction of Logiq Systems.

Who we are today: Logiq Systems was founded in 2020 and is currently a team of five. Our passion and mission is improving the world around us, making it better for people and the planet. Our purpose pushes us to be the force of change in this industry. Not just in environmental sustainability by making the world less polluted from carbon, noise and poor air quality, but also in creating a supportive company flexible to the realities of modern life. A company with a diverse, equal, and respectful workforce.

We are remote-first: As a team we are spread across the UK from Edinburgh to London, this means we can work with the best people out there. We also recognise the importance of building a sense of team, meeting regularly (at least once a quarter) and put a lot of emphasis into team building in the 'virtual' work environment also - e.g. daily team video calls, non-work Slack channels.

Flexible working: To manage the interface of life and work we operate a flexible working policy, at the start of every week we have a whole team standup and in that we clearly communicate as a team what commitments people have that might cut into the working day or lead to a hard stop at the end of the day.

Supporting women and primary carers in tech: Both founders fully recognise the importance of building a supportive working environment for women and parents so they can continue a career, while remaining supportive and attentive to both kids and work.

The team we want to build is one where we are:

• Passionate about making a difference.
• Flexible and comfortable with ambiguity.
• Extremely self-motivated with a strong work ethic.
• Fun!
• Humble, authentic, and honest.
• Comfortable being challenged.
• Curious.

The Role: As a Senior Software Engineer, you will be responsible for the long-term technical direction of the Logiq platform and products, which provide real-time operational intelligence for connected clean energy assets. You will be designing and developing new products, features and improvements to the Logiq platform, delivering value to our growing customer base and the key capabilities required to evolve our growing business. You will also be the champion of software engineering best practices across Logiq Systems.

A few of your responsibilities:

• Design and develop full-stack features using React, Python, PostgreSQL and serverless technologies (AWS Lambda, Fargate).
• Design and implement RESTful APIs and event-driven systems.
• Maintain, extend and improve optimisation, alerting and forecasting models.
• Implement and maintain CI/CD pipelines.
• Ensure high-quality code through peer reviews, automated testing, documentation and adherence to software development standards.
• Take ownership of the technical architecture and engineering processes.
• Collaborate closely with a small startup team.

To thrive in this role: We expect you to:

• Be comfortable with variety and shifting priorities.
• Take ownership of outcomes, not just tasks.
• Balance quality with speed.
• Ask questions and challenge ideas respectfully.

What you'll need to do this job:

• Proven experience in full-stack software development.
