Your Impact as a Staff Backend Engineer

Are you ready to make a significant impact in a fast-paced, autonomous environment? We're seeking an exceptional Staff Backend Engineer to join our cross-functional product team in Warsaw.

What You'll Do:

* Technical - this is a heavily technical role; hands-on coding skills are expected. It’s not a management role

* Leadership - Own and deliver cross-team and cross tribal technical initiatives

* Architectural - Take ownership of architecture for a tribe

* Guidance - Sought out for technical guidance; anticipating technical issues at the product level and making architectural and design decisions to avoid them

* Improvements - Create sweeping improvements in stability, performance and scalability across major business-critical systems

* Delivery - Ensure timely delivery of your team’s projects, which will ultimately have a tangible impact on Fresha’s success

* Lead-by-example - Make sure your team follows our engineering practices by leading from the front

* Collaboration - Work closely with diverse functions within the team across Product, Design, Data and QA and make sure that the team has clear goals and regularly delivers value to our users

* Learning - Facilitate continuous learning and improvement for your team

* Standards - Make sure that the systems your team owns meet Fresha quality, reliability and scalability standards

* Innovative - You will be anticipating broad technical changes and ensuring Fresha is always ahead of the curve

* Strategic - Recognising and making trade-offs concerning the whole system. You have a deep understanding of the entire architecture for a significant part of our business, and you’re able to articulate clearly the scaling and reliability limits of that area.

* Multiplier - Primarily acting as a multiplier by building systems, authoring tools or introducing policies or patterns that raise the level of productivity of the entire organisation

* Communication - Communicating the awesomeness of Fresha in different Tech communities externally via talks and blog posts, identifying areas that we can share effectively with the outside world, guiding the creation of content and communication around those areas. Leading conversations internally about the direction of significant areas of technology, driving wide-team consensus on the adoption of this direction and using this direction to inspire engineers

This list is not exhaustive, and there may be other activities you are required to deliver.

AI-Augmented Workflow: You have deep experience building and interacting with AI agents, using them to amplify your output to 5x that of manual coding. You are able to integrate agents into our workflow while strictly adhering to our architecture and security standards, taking full accountability for ensuring all generated code meets the quality expectations of a Senior Engineer.

Delivery - You have consistently delivered large systems involving one or more teams’ contributions on time at a high level of quality

Strategy - Played a key role in developing multi-year technology strategy for complete and critical areas of the business that encompass multiple systems and teams

Adaptability - You have created an architecture that enables many potential futures without knowing exactly what the future is

Relationships - Ability to interact with people from across the business and build strong relationships, including the ability to effectively influence upwards

Facilitation - Listened and guided debates to help reach consensus; once a decision is made clearly communicate the decision(s) back

Planning - Set short to medium-term strategic technical direction, able to look ahead 6-12 months identify areas of greatest need and create plans to improve them
