Leading creative agency specialising in sustainability, environment, energy and technology

Our client is looking for a motivated individual with a passion for web development and a keen eye for detail to join their fast-paced development team on a full time, permanent basis. Projects often involve educating and influencing audiences around key challenges, such as the global move to sustainable energy systems. Your work will be seen and used by a global audience to make a positive difference to the world we live in.

As an agency with a history of retaining and nurturing their people, the right candidate will have excellent long term career prospects within the company. If you are a driven, ambitious individual with a strong agency background, passionate about self-improvement and ready to take the next step in your career, we would love to hear from you!

You’ll work closely with their senior developers to build and maintain a range of digital applications using HTML, CSS, and JavaScript. This role offers a great opportunity to learn, grow, and advance your skills in a supportive environment.


About You:

Portfolio: You have the knowledge and experience to produce well thought out and rationalised solutions. Your work should be able to demonstrate this through 2-3 project examples, your own personal site and/or GitHub profile.

Technical skills & knowledge: You’re proficient in modern web development technologies, with strong skills in HTML, CSS (SCSS), and JavaScript. Experience with frameworks such as Bootstrap, Tailwind, React and/or Next.js is a plus. You are adept at translating Figma designs in to working solutions and a solid understanding of responsive website development (Flexbox/Grid) is essential, along with knowledge of web accessibility best practices. You are curious about how AI can support the development process including testing, documentation and creating efficiencies.

Problem-solving: You relish putting your problem-solving skills into practice and have the confidence to work unaided to find suitable solutions / propose alternatives as needed. You adapt to feedback (from clients, or our production lead) and iteratively improve your work accordingly.

Time management: You are highly organised with an ability to manage multiple projects simultaneously, along with a keen sense of prioritisation and time management from both a deadline and client budget perspective. You take a proactive and flexible approach, that can adapt to demanding business needs and have the confidence and ability to work quickly and efficiently to deadlines, without impacting quality or attention to detail.

Team / collaboration: You thrive whether taking ownership of your own projects or working with others. You are confident when taking the lead on a project and capable of making your own decisions whilst also delivering value in a more supporting and collaborative role where necessary. You collaborate smoothly with colleagues across different time zones, making the most of overlap while protecting focused development time.

Communication: Your verbal and written communication skills are excellent, allowing you to clearly articulate your technical approach and solutions to team members, project managers and clients alike.

£80,000 - £100,000
RECENTLY POSTED

Remote-first (UK) | £80,000-£100,000 + equity

We’re hiring for a UK cyber security startup building a platform that helps organisations detect malicious open-source code and secure their software supply chain in real time.

The product continuously scans dependencies, surfaces risk clearly, and helps teams prevent compromised packages from entering the codebase - without slowing engineering down.

If you’re a strong full stack engineer who enjoys building clean, scalable product and you’re curious about cyber security, this is a chance to build something genuinely important.

Why this is interesting (especially if you like cyber)

Open source and third-party dependencies are now one of the biggest attack paths for modern organisations.

This team is tackling that head-on with a platform designed for both engineering and security teams - offering malware detection, deep dependency visibility, and policy enforcement to stop bad code early.

They’re also part of a leading UK cyber security accelerator programme, supporting the next generation of high-growth security startups.

The role

You’ll join a small, high-output engineering team and build customer-facing features end-to-end - front to back to cloud.

You’ll ship frequently, own features, and have real influence over architecture and product direction.

This role includes LLM exposure, but the emphasis is practical integration via APIs (plugging LLM capabilities into workflows), not building research-heavy or RAG-first systems.

What you’ll do

Build and ship product features across the stack (UI → API → cloud)
Develop back-end services in Python, delivering reliable, well-tested APIs
Build responsive, intuitive front-ends in React
Work within an AWS serverless environment (event-driven services, APIs, scalable data patterns)
Integrate external services (including LLM APIs) to enhance workflows and automation
Collaborate closely with founders and product to shape requirements and deliver fast
Improve reliability, performance, monitoring, and developer experience as the product scalesWhat you’ll be building (product context)

The platform focuses on software supply chain security, including capabilities such as:
Detecting malicious or tampered open-source packages
Providing deep insight into dependency trees and hidden risk
Preventing compromised code from reaching production environments
Helping organisations enforce security policies early in the SDLCWho you are

You’re a capable Full Stack Developer who has:
Strong commercial experience building web applications with React and Python
Hands-on experience in an AWS Serverless setup (Lambda, API Gateway, DynamoDB, event-driven architectures)
Confidence integrating external APIs, including modern LLM/AI services
A product mindset: you care about usability, clarity, and shipping value
Comfort working in a startup environment - ownership, pace, and ambiguity
An interest in cyber security or secure software development (no need to be an AppSec specialist already)Tech stack (high level)

Frontend: React
Backend: Python (APIs/services)
Cloud: AWS Serverless
AI: LLMs via API integrations (workflow enhancement + automation) experience is beneficial
Package

£80,000-£100,000 base salary (depending on experience)
Equity opportunity
Remote-first across the UK with flexibility and autonomy
High impact: your work will directly shape the platform and customer experienceInterested?

Become the founding member of this medical device software development team

On the borders of Essex and Cambridgeshire, this diagnostics company develops medical instrumentation that provides accessible and timely results for public health purposes. Their system uses a combination of embedded C running on an RTOS, A React-Native app running on Android, and centralised data collection based on the LAMP stack and MariaDB.

With products already on the market, they are seeking to move their software development in house, and are seeking an experienced and adaptable Senior Software Engineer to form the nucleus of their software team. The process of taking on board software development will be gradual, and supported by current (external) developers, so immediate familiarity with the entire stack isn’t expected; however, a strong understanding of embedded development, and prior experience of developing software for medical devices (and therefore a knowledge of the associated medical software standards) will be needed.

As the company is still at an early stage, you may be occasionally required to help out in other (non-software) functions of the company - you will therefore need an accommodating and adaptable outlook as well as an enthusiasm for work which will have a very substantial positive impact.

You will need:

* A strong academic background in Computer Science, Electronics or similarly applicable subject.

* Substantial experience as a software engineer, including software development for medical devices.

* Excellent coding skills in embedded C.

* A can-do attitude, happy to dive into new technologies and learn new skills as needed (or indeed to help out with non-software tasks as the need occasionally arises).

* Full existing right to work in the UK without restriction, time limit, or sponsorship.

Not essential, but useful: real-time operating systems, React Native, Android, LAMP, C# or Python.

If you’re looking for a role that will make a massive positive impact in the world, whilst at the same time becoming the founding member of a software team, then this may be for you. The role is on-site in a pleasant countryside location. A highly competitive salary is on offer to the successful candidate.

Medical Device Software Engineer
ECM Selection (Holdings) Limited
Cambridge
In office
Senior
£70,000 - £80,000
+1

Become the founding member of this medical device software development team

On the borders of Essex and Cambridgeshire, this diagnostics company develops medical instrumentation that provides accessible and timely results for public health purposes. Their system uses a combination of embedded C running on an RTOS, A React-Native app running on Android, and centralised data collection based on the LAMP stack and MariaDB.

With products already on the market, they are seeking to move their software development in house, and are seeking an experienced and adaptable Senior Software Engineer to form the nucleus of their software team. The process of taking on board software development will be gradual, and supported by current (external) developers, so immediate familiarity with the entire stack isn’t expected; however, a strong understanding of embedded development, and prior experience of developing software for medical devices (and therefore a knowledge of the associated medical software standards) will be needed.

As the company is still at an early stage, you may be occasionally required to help out in other (non-software) functions of the company - you will therefore need an accommodating and adaptable outlook as well as an enthusiasm for work which will have a very substantial positive impact.

You will need:

  • A strong academic background in Computer Science, Electronics or similarly applicable subject.
  • Substantial experience as a software engineer, including software development for medical devices.
  • Excellent coding skills in embedded C.
  • A can-do attitude, happy to dive into new technologies and learn new skills as needed (or indeed to help out with non-software tasks as the need occasionally arises).
  • Full existing right to work in the UK without restriction, time limit, or sponsorship.

Not essential, but useful: real-time operating systems, React Native, Android, LAMP, C# or Python.

If you’re looking for a role that will make a massive positive impact in the world, whilst at the same time becoming the founding member of a software team, then this may be for you. The role is on-site in a pleasant countryside location. A highly competitive salary is on offer to the successful candidate.

Another top job from ECM, the high-tech recruitment experts.
