Mission Overview:

Join Keystone Solutions as a Senior Full-Stack Software Engineer on a consultancy mission with our client. You will help build the Evidence-Based Prevention (EBP) platform—an ambitious initiative to strengthen health prevention by strictly relying on validated scientific evidence and recognised clinical guidelines. As a Keystone Solutions consultant, you will work closely with the client to identify personalised prevention signals for members and/or their healthcare providers, covering all stages of prevention (from primary to quaternary prevention). The platform for the EBP will be AWS, and you will engineer the various application components end to end.

Consultancy Nature of Work:

As a Keystone Solutions consultant, you will operate in a consultancy model: collaborating on-site and remotely with the client’s teams, adapting to their environment, and delivering high-impact solutions under Keystone Solutions quality standards. You will represent Keystone Solutions at the client site, bringing best practices, craftsmanship, and a pragmatic mindset to every engagement.

Dynamic Projects:

Through Keystone Solutions, you will engage with diverse technical and functional challenges across client initiatives. This role offers exposure to scalable architectures, data-intensive workloads, and full-stack development within cloud-native ecosystems, enabling you to broaden your experience across multiple client scenarios over time.

Turbo-Charged Learning and Development:

We champion continuous improvement. As a K-Stone consultant, you will benefit from hands-on mentorship, curated learning paths, certification support (e.g., AWS Associate Developer), peer communities of practice, and regular knowledge-sharing sessions—accelerating your growth in architecture, DevOps, data engineering, and front-end excellence.

Ambition Skyrocketing within a Consultancy Framework:

Keystone Solutions fosters career progression through meaningful client engagements. You will take initiative, own outcomes, and shape technical direction while building a portfolio of achievements across projects—fast-tracking your evolution from senior engineer to architectural and leadership tracks within our consultancy.

Key Responsibilities:

• Identify and understand business requirements and translate them into pragmatic, maintainable applications for the client.
• Do whatever it takes to help deliver the Evidence-Based Prevention building blocks: coding backend logic, developing screens, monitoring quality, and reducing costs.
• Engineer and integrate application components on AWS as part of the EBP platform.
• Collaborate within a dynamic and autonomous team to realise the project’s vision and outcomes.

All responsibilities above will be performed as a Keystone Solutions consultant, embedded with the client and operating under our consultancy model.

Required Profile (carried out as a Keystone Solutions consultant):

• You have a wealth of best practices at your disposal and know when to apply which tool. A few certifications (e.g. AWS Associate Developer) are useful.
• As a software professional, you can use any language and any framework. We use Typescript, Python & AWS as our building blocks. We use Angular for our front-end. We are looking for a full stack developer for this vacancy.

• You can demonstrate solid experience in similar projects, where performance and large transaction volumes were key.
• You are persuasive thanks to your flexibility, smooth communication style and professional knowledge. You stand out thanks to your sense of analysis and synthesis, combined with a high-quality and customer-oriented attitude. Ee
• You impress with your flexibility, smooth communication style and professional knowledge. You distinguish yourself through your analytical and synthetic skills, combined with a high-quality, customer-oriented attitude. You see deadlines as a challenge. You are enthusiastic, creative and dare to take initiative. You work independently, but are also a team player.
• You have strong analytical and problem-solving skills.
