Senior Software Engineer - AI Team

Teamwork.com 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. The AI Team is a specialist enabling team at the heart of how Teamwork builds intelligent product. We’re responsible for the infrastructure, frameworks, and engineering capabilities that every product team depends on to ship AI-powered features and workflows. We don’t just build AI — we make it possible for the entire engineering organisation to build with AI confidently, consistently, and at pace. If you want to shape the foundations that a whole product is built on, this is the team.

• Design, build, and maintain the core AI infrastructure, frameworks, and shared services that product teams across Teamwork rely on to deliver AI-powered features.
• Develop and evolve APIs, SDKs, and integration patterns that make it straightforward for teams to embed AI capabilities into their product areas.
• Build and maintain evaluation frameworks (evals, benchmarks, quality metrics) that give teams confidence in AI feature quality before and after release.
• Work across backend (Node/Go) and frontend (Vue 3) where needed, with a primary focus on backend systems, data pipelines, and AI service layers.
• Collaborate with product teams to understand their AI needs, unblock adoption, and ensure the platform capabilities evolve alongside product requirements.
• Work with LLM providers, embedding models, vector stores, and retrieval pipelines — selecting, integrating, and optimising the right tools for each use case.
• Bring AI features to production, instrument them for real-world performance, and iterate based on customer feedback and usage data.
• Use AI tools throughout your own development workflow to accelerate delivery, improve quality, and reduce manual effort.
• Contribute to engineering culture by documenting patterns, sharing best practices, and raising the AI capability of the wider engineering team.
• Continuously improve how we build and ship AI — optimising for reliability, quality, speed, and customer impact.

Skills You’ll Bring

• Strong product mindset — you understand that AI infrastructure exists to serve product outcomes, and you make decisions that balance technical rigour with customer and business impact.
• Ability to critically evaluate AI outputs, design effective prompts and pipelines, and build systems that degrade gracefully when models behave unexpectedly.
• A sharp eye for AI quality — you know how to define what “good” looks like for an AI feature, measure it, and systematically improve it.
• Solid engineering fundamentals: system design, performance, scalability, and maintainability.
• Strong problem-solving and debugging skills, particularly in systems where behaviour is non-deterministic.
• An enablement mindset — you get satisfaction from making other teams more capable, not just shipping your own features.
• Clear, direct communication and a collaborative working style.
• Ownership mindset — you focus on delivering outcomes, not just output.

What Sets You Apart

• Experience building AI features end-to-end: from problem definition and design, through implementation, evaluation, launch, and iteration based on real customer feedback.
• Experience building shared AI platforms, frameworks, or internal tooling that other engineering teams consumed.
• Familiarity with evaluation and observability practices for AI systems — evals, A/B testing, monitoring for drift, hallucination detection, and quality regression tracking.
• Experience with our infrastructure stack: AWS EKS, RDS/MariaDB, DocumentDB, OpenSearch, RabbitMQ.
• Experience with Go and Vue 3 specifically, or a strong appetite to ramp up quickly.
• A habit of staying current with the rapidly evolving AI landscape and bringing practical insights back to your team.

A Note on AI

This role has a dual AI expectation. First, like every engineer at Teamwork, you’ll be expected to use AI tools actively in your own workflow — to write, review, test, and ship code more effectively. Second, and specific to this role, you’ll need to demonstrate real experience building AI-powered product features: designing them, evaluating them, shipping them, and improving them based on what customers actually experience. During the interview process, we’ll ask you to walk us through concrete examples on both fronts. We’re not looking for enthusiasm about AI — we’re looking for evidence.

Benefits

• Up to 30 days vacation.
• Pension/Retirement matching.
• Health plans and wellbeing programs.
• Give Back program.
• Educational resources and generous development allowance.
• Inclusive policies including maternity, paternity and parent leave.
• Recognition programs.
• Employee Share Options (ESOP).
