Who are we?

At Qflow we’re on a mission to transform one of the world’s most impactful industries, Construction.

We’re providing easily captured, data-driven insights, empowering the industry to make better decisions, ultimately delivering increased quality, efficiencies, cost savings, and cost and risk avoidance.

We’ve built a cutting-edge platform that gives project teams real-time insights into materials, waste, cost, carbon, and quality right at the source.

Using AI, machine learning, and smart integrations, our tech makes sense of chaotic data streams by extracting information from messy receipts and documents, auditing it against project requirements, flagging risks instantly, and feeding insights directly into reporting workflows.

Our mobile app makes it effortless for workers on the ground to capture data in seconds turning construction sites into real-time, data-rich ecosystems.

The impact? Less waste. Lower carbon. Smarter decisions. A construction industry that uses only what it needs, building a future that works for people and the planet.

We’re backed by leading climate-tech and construction-tech investors, including Systemiq Capital, Greensoil Prop Tech Ventures, and Suffolk Technologies, and have raised £11.2M in Series A funding to accelerate our international growth.

You should apply if …

You’re an Engineer who wants to use your skills for impact, helping make one of the world’s most polluting industries more efficient, sustainable, and data-driven.

You enjoy solving complex, messy data challenges, turning raw information into reliable insights and AI-powered features that deliver measurable results.

You’re curious, collaborative, and want to work in a place where your work directly contributes to how construction companies reduce waste, carbon, and cost at scale.

Your team and your role

We’re looking for a Software Engineer to join our Data Experience Team.

This team prototypes, designs, develops, and deploys scalable, data-driven solutions powering Qflow’s platform.

Reporting to our Engineering Manager, and working closely with our Tech Lead, you’ll balance innovation and delivery, researching and shaping early prototypes into robust, production-ready features that take our product to the next level.

Here’s what you’ll do day to day

• Research, prototype, and productionise solutions that deliver real business impact.
• Maintain high standards in code quality, testing, documentation, and reproducibility.
• Collaborate with Product and other engineers to identify opportunities and translate them into robust, data-driven solutions.
• Perform exploratory data analysis (EDA) to identify patterns, validate assumptions, and define approaches on what to build.
• As a team member, create new data-related services, integrating them into APIs, pipelines, and Qflow’s wider system architecture.
• Contribute to data governance practices, including versioning, lineage, and validation.
• Share knowledge, mentor peers, and help embed a culture of data-driven thinking and continuous improvement across the team.
• Our tech stack

The Data Experience Team works with Python and SQL for data processing, Azure and Terraform for cloud infrastructure, and modern ML/AI tools such as Open AI and Gemini.

We’re continuously raising our engineering standards through robust testing, CI/CD, and shared code quality practices.

We value curiosity and innovation, always exploring new technologies to stay ahead of the curve.
