Senior Software Engineer

Engineering

is the AI-powered platform that helps client‑services organisations deliver work profitably. From project management and resource planning to time tracking and financial oversight, we give agencies, consultancies, and professional services teams everything they need to stay organised, run efficiently, and protect their margins. Our mission is to make every team that delivers client work more productive and more profitable — and we’re building AI into every layer of the platform to make that happen.

This is a remote employment contract role in Poland only.

We’re looking for experienced engineers who build products that customers love and who use AI as a core part of how they work. This is a hands‑on role where you’ll design, build, and ship features across the full stack, working closely with product and design to solve real customer problems. You’ll bring strong backend skills and enough frontend fluency to deliver end‑to‑end.

You’ll also bring a clear track record of using AI tools to move faster, build better, and raise the bar on quality.

• Design, build, and deliver product features that create clear, measurable value for customers
• Work across backend (Node/ Go) and frontend (Vue
  3) to ship high‑quality, intuitive user experiences
• Develop scalable APIs, services, and systems in a cloud‑native environment (AWS: EKS, RDS/Maria
  
  DB, Document
  
  DB, Open Search, Rabbit
  
  MQ)
• Collaborate closely with product and design to deeply understand customer problems and translate them into effective solutions
• Take ownership of features end‑to‑end, from concept through production, iteration, and improvement
• Use AI tools throughout the development lifecycle to accelerate delivery, improve quality, and reduce manual effort, from requirements analysis and design through to implementation, testing, and code review
• Build and maintain automated tests to ensure reliability, performance, and confidence in releases
• Contribute to engineering culture by sharing what works, whether that’s a better AI workflow, a smarter testing approach, or a cleaner architectural pattern
• Continuously improve how we build software, optimising for speed, quality, and customer impact

Experience You’ll Bring

• Strong experience delivering customer‑facing features in a SaaS product environment
• Backend expertise in Node/Go or a similar with experience building scalable APIs and services
• Solid experience with modern JavaScript frameworks (Vue, React, or similar), with the ability to deliver production‑ready UI work; full‑stack engineers are strongly preferred, but deep backend engineers with working frontend proficiency are equally welcome
• Hands‑on experience with cloud infrastructure and distributed systems on AWS or similar (containers, managed databases, message queues, search)
• Familiarity with relational databases (e.g. Maria
  
  DB/MySQL) and No
  
  SQL data stores (e.g. Document
  
  DB, Open Search)
• Demonstrated, active use of AI tools (e.g. Claude, Copilot, Cursor, or similar) to improve how you work, from writing and reviewing code, to exploring designs, testing, debugging, and documentation
• Experience working in cross‑functional teams to deliver product improvements from idea through to release

Skills You’ll Bring

• Strong product mindset - you make decisions that balance technical quality with customer and business impact, not just engineering elegance
• Ability to use AI effectively in day‑to‑day work, while critically evaluating outputs, maintaining high standards, and knowing when human judgement matters most
• Solid engineering fundamentals: system design, performance, scalability, and maintainability
• Ability to work across the stack, or deep backend expertise paired with confident frontend delivery
• Strong problem‑solving and debugging skills in complex, distributed systems
• Clear, direct communication and a collaborative working style
• Ownership mindset - you focus on delivering outcomes, not just output
