Staff Backend Engineer

Project overview

Hello,

We are called People More because we treat our employees with respect, but also because the projects we work on are for people and should be easy and pleasant to use. We are technological, but we look at the bigger picture :)

The company is made up of people with a huge client base in the country and abroad, for whom we build projects from scratch (UX, UI, frontend, backend, mobile) or in part. We work directly for our clients and also support our partners in their own solutions. This ensures a wide range of projects and the ability to change! We work with clients all over the world.

For the project that we are working on with our partner, we are looking for Staff Backend Engineer.

Your duties will include:

• Designing and evolving backend architecture across multiple teams, ensuring clear domain boundaries, reliable service communication, and scalable system design.
• Establishing architectural principles for distributed systems, including event-driven communication, state management, data consistency, and API integration.
• Leading technical discussions and documenting architectural decisions through ADRs, RFCs, and technical design proposals.
• Assessing technology options and recommending appropriate solutions for databases, cloud infrastructure, messaging systems, and financial data processing.
• Developing and improving AI-powered engineering workflows, including agentic development tools, adoption monitoring, performance measurement, and continuous optimisation.
• Identifying opportunities to improve engineering practices, modernise existing solutions, and introduce common technical standards across teams.
• Collaborating with engineering leaders and product stakeholders to ensure that technical solutions align with business objectives and long-term platform strategy.
• Supporting experienced engineers through architectural reviews, technical mentoring, knowledge sharing, and design discussions.
• Driving cross-team technical initiatives and supporting the implementation of architectural improvements across the organisation.
