Prevail's PSO team builds the tools and platforms of our technology landscape, used day to day by the intelligence analysts behind our client investigations. Today these solutions are highly specialised and application-specific, but they share the same backend core: Databricks, AWS and Python, with React on the frontend where needed. We're bringing these tools together into a single, consolidated intelligence platform, and this role will play a part in that evolution. As a Full Stack Engineer, you'll design, build and maintain the applications that power our business - from APIs and services on our Python and AWS backend, through to the user interfaces intelligence analysts use directly, some of which are built in React. Our ambitions go beyond internal tooling: we're building towards a broader platform offering that, over time, we expect to extend to clients as well, and you'll play a part in shaping that as it grows. You'll work closely with the rest of the engineering team to turn requirements into reliable, well-engineered software. This is a mid-level role suited to someone with solid full stack experience who is comfortable owning features end to end, wants to help shape a growing platform, and is motivated by building tools that have a genuine, tangible impact on real investigations. We're looking for someone who can find the balance between pragmatism and craftsmanship, knowing when to move fast and when to invest in the right foundations., * Design, build and maintain full stack features across our Databricks, Python and AWS backend and the frontend of our internal tools, several of which are built in React. * Work with Solution Engineers and analysts to understand requirements and translate them into well-architected, maintainable technical solutions. * Build and maintain APIs and services on AWS that power our internal tools. * Contribute to the ongoing consolidation of our application-specific tools into a single intelligence platform, helping define shared components and patterns. * Write clean, tested, well-documented code, and participate in code review to help raise the bar across the team. * Take ownership of features from design through deployment, including monitoring and support once in production. * Diagnose and resolve technical issues by working directly across the business to identify root causes. * Help evolve our engineering practices, tooling and CI/CD processes as the team and platform grow. * Mentor junior colleagues and contribute to a collaborative, high-standard engineering culture. * Maintain high standards of data security and information handling given the sensitive nature of the intelligence and client data our tools support. ## Related Videos - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Navigating the Future of Junior Developers in Tech](https://www.wearedevelopers.com/videos/1280-navigating-the-future-of-junior-developers-in-tech) - [PySpark - Combining Machine Learning & Big Data](https://www.wearedevelopers.com/videos/44-pyspark-combining-machine-learning-big-data) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) ## Related Articles - [Fullstack Developer Salary UK](https://www.wearedevelopers.com/magazine/251-fullstack-developer-salary-uk) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe)
