Employment Type: Full-time employment in Poland through our Employer of Record (EOR) partner, under a local employment contract.
ABC Fitness is building AI-enabled product experiences that help fitness operators move faster, make better decisions, and create better outcomes for their customers and members. As a Senior Software Engineer, AI Product Incubation, you will join a new Poland-based embedded product squad focused on bringing new AI capabilities from idea to market.
This is a product engineering role, not an AI research or platform role. You will build on top of ABC’s existing AI platform services, including our gateway, evaluation framework, retrieval patterns, and guardrails, so your focus can stay close to the customer problem, the product experience, and the measurable outcome.
You will report to an Engineering Leader and partner closely with Product, Design, Data, AI platform, and other engineering teams to ship AI-enabled features that are useful, trusted, measurable, and commercially ready.
WHAT YOU'LL DO
Build customer-facing AI product capabilities from early concept through production release, usage measurement, and iteration.
Turn ambiguous product opportunities into small, testable slices that can be validated with real users, real data, or real customer workflows.
Partner with Product and Design to define what “good enough” means for AI-enabled experiences based on user need, workflow risk, and customer impact.
Use existing AI platform capabilities, including retrieval, evaluation, guardrails, prompts, models, and observability, to deliver reliable product experiences without owning the platform itself.
Ship features behind flags, monitor early usage and quality signals, and improve the product based on what customers actually do.
Design graceful failure paths for moments when AI output is wrong, slow, incomplete, or unavailable.
Use AI-assisted development tools responsibly to increase speed while reviewing, testing, and owning the code you ship.
Support production readiness, operational follow-through, and incident learning for the capabilities you deliver.
WHAT YOU'LL NEED
Experience shipping customer-facing software products to real users in a production environment.
Hands-on experience building or contributing to AI-enabled product features, not only demos, proofs of concept, internal tools, or prompt experiments.
