Experience

  • JobRad Austria
    Product Owner
    May 2024 - December 2025 (1 year and 7 months)
    Vienna, Austria
    Owned the full product function for the Austrian market of a fast-growing B2B bike-leasing platform —
    building product structures, processes, and delivery capability from scratch in a newly established subsidiary.
    • • Built the product roadmap and backlog infrastructure, taking end-to-end ownership of prioritisation, OKR definition, and delivery alignment across an 8-person cross-functional team — without direct line management authority.
    • • Led a high-stakes migration to a new external Insurance provider, managing scope, stakeholder expectations, and technical dependencies across teams to deliver a fully operational product setup without disrupting live operations.
    • • Established sprint rituals and a continuous refinement process that significantly reduced carryover between cycles and gave engineering and operations a shared, trusted prioritisation framework.
    • • Identified and drove scalability improvements that reduced manual operational overhead, directly freeing up team capacity for higher-value product and customer work.
    • • Served as the single point of contact between C-level leadership and engineering, independently translating company strategy into OKR-driven product initiatives
    • • Delivered the technical and product-side onboarding infrastructure for enterprise customers with 5,000+ employees — enabling Sales to close and operationalise large-account deals without manual product intervention.
  • JobRad Austria
    Business Analyst
    January 2022 - May 2024 (2 years and 4 months)
    Vienna, Austria
    Owned end-to-end delivery of key product and digitalisation initiatives across product, IT, and operations —
    acting as project lead on multiple workstreams in a fast-scaling market-entry environment.
    • • Conceived and delivered full digitalisation of the end-to-end contract workflow across sales, leasing bank, and customers using Salesforce + DocuSign — cutting contract turnaround from 14 days to 3–4 days (~75% faster) and reducing error rate from 30% to under 5%.
    • • Architected and led the integration of 5+ third-party APIs, connecting external partners into a unified and maintainable system landscape — reducing new partner onboarding time by an estimated ~60%.
    • • Drove product trade-off decisions across delivery speed, technical debt, and scalability — taking ownership of outcomes rather than escalating, in a team of ~8 with no dedicated product manager above.
    • • Took ownership of onboarding and mentoring new team members — reducing estimated ramp-up time by 3–4 weeks through structured documentation, process walkthroughs, and direct knowledge transfer.
