About ONNI

ONNI is a young hair care brand, born out of a love for the product. Our founder, Stefanie Wirnshofer, created ONNI because she wanted to develop products she could wholeheartedly stand behind. Today, onni.de brings together our brand world and features products we use ourselves every day.

And we do it our way: ONNI is completely bootstrapped. We are financed exclusively through our own investment company, without private equity and without external investors in the background. Nobody tells us what to do. We create products out of love, make our own decisions, and are incredibly successful doing so.

We work fast, lean, and with a modern tech stack: Shopify, Klaviyo, Meta Ads, Klar Attribution, and our own analytics setup. Numbers are a tool for us, not an end in themselves. Ultimately, what matters is the product and the person using it.

We are AI first. And we really mean it.

Almost every job ad today claims "we use AI". For most, this means the team can use ChatGPT for product texts. For us, it's the operating mode.

Our entire e-commerce operation is AI-supported and AI-controlled. Not as a gimmick, but as an operating system: data preparation, reporting, and routine processes across the shop, performance, CRM, analytics, and operations run automatically in the background.

Area What the Agent Does
Shop & Theme Shopify templates, landing pages, sales pages, product data
Performance Meta Ads, Google Ads, budget and creative analyses
Marketplaces Amazon SP API, TikTok Shop
CRM Klaviyo flows, segments, campaign reporting
Analytics Attribution via Klar, GA4, custom dashboard on Supabase
Operations Fulfillment monitoring, inventory tracking, returns analysis
Finance Invoice processing, business analysis evaluation, cost analysis
Support & SEO Ticket automation, technical SEO, content audits

What does NOT happen here: Nobody compiles a report in Excel in the morning. Nobody exports CSVs to compare numbers. Nobody writes standard emails by hand.

What happens instead: The systems pull data from the channels themselves, crunch the numbers, identify anomalies, and present you with a ready-made decision template in the morning. Your job is to review it, challenge it, and make a decision, not to create it.

What this means for your career: You will learn how to run an AI-supported shop: delegating processes, questioning results, constantly rethinking tooling. This is the skill that every e-commerce role will demand in two to three years. You will build it with us today, in real operations, with real revenues.

You don't need to be able to code for this. You need to be enthusiastic about working this way and willing to regularly overhaul your own working methods because the tooling improves faster than processes age.

Two specialist agencies directly by your side

Paavo Christian Spieker — CEO ONNI Brands Group

ONNI is part of the ONNI Brands Group GmbH, and the group includes two specialized agencies with whom you will work side-by-side, instead of emailing them as external service providers:

  • One Beyond Search: Technical SEO and AI Search from Munich. Best-in-class SEO meets real coding know-how: page speed, Core Web Vitals, complex shop architectures, and visibility in AI search.
  • One AI Commerce: Enterprise e-commerce and performance consulting for D2C brands on Shopify Plus. Operationally implemented in code, pipelines, and dashboards, not just as a slide.

For you, this means: you have direct access to the resources, know-how, and teams of both subsidiaries. While others are on the phone with just one agency, you have senior SEO and performance expertise in-house. You gain exactly the knowledge you need for your tasks and grow with projects that go far beyond a classic e-commerce role.

You report directly to Paavo Christian Spieker, CEO of the ONNI Brands Group. Paavo is not a distant boss: he is deeply involved in e-commerce and performance marketing daily, with genuine passion for numbers, campaigns, and growth. For you, this means: you learn directly from someone who truly lives the craft, as well as from the teams of our two specialist agencies. If you want to grow, you'll find an environment here where know-how isn't hidden in slides but sits right next to you.

Your Role

As an E-Commerce Manager (m/f/d), you are the link between the shop, performance, and CRM. You are responsible for the end-to-end customer journey: from the first ad to the product page to the repurchase email. You work closely with the performance, creative, and operations teams and have a direct impact on revenue, margin, and customer loyalty.

This role is deliberately broad: you are an all-rounder with a desire to dive into multiple disciplines, not a specialist for just one platform.

Your Responsibilities

  • Shop & Assortment: You manage our Shopify store: product listings, landing pages, promotions, and checkout optimization. CRO is not a buzzword for you, but daily business.
  • Performance Marketing: Together with the team, you manage our Meta and Google Ads accounts, brief creatives, analyze CAC/ROAS, and identify scaling levers.
  • CRM & Email Marketing: You build and optimize Klaviyo flows (welcome, abandoned cart, post-purchase, winback) and campaigns, segment audiences, and drive retention and LTV.
  • Reporting & Analysis: You work with Klar, Shopify Analytics, and our internal dashboard. You derive measures from data and share insights clearly and concisely with the team.
  • Promotion and Launch Planning: You plan promotional periods (BFCM, sale phases, product launches) together with the creative, performance, and operations teams and ensure clean execution.
  • Cross-functional Projects: You work closely with customer service, logistics, and the brand team to solve pain points along the customer journey.

Your Profile

  • 2 to 4 years of relevant experience in e-commerce, ideally in a D2C brand, a performance agency, or a marketplace setup.
  • Solid hands-on experience with Shopify (theme adaptations at a light code level are a plus, not a must).
  • Strong understanding of performance marketing mechanics: Meta Ads Manager, Google Ads, attribution, funnel logic.
  • Experience with email and CRM tools (Klaviyo preferred): setting up flows, A/B testing, segmentation.
  • Data-savvy: proficient in Excel and Google Sheets, ideally initial exposure to BI tools, Looker Studio, or SQL.
  • Open to AI-supported work: You don't just use ChatGPT and co. to rephrase texts, but are keen to build actual work processes with them. Prior experience with AI tools is a plus, curiosity is sufficient.
  • Structured, independent way of working: You don't wait for tickets but identify problems yourself and solve them.
  • Very good German (C1+) and solid English, both written and spoken.

What We Offer

  • Direct Impact: Flat hierarchies, short decision-making paths, and visible impact of your work on revenue and roadmap. You report directly to the management.
  • Learning Curve: You work cross-functionally, gain insights into all brand and marketing disciplines, and grow with the role.
  • AI first from day 1: You work with an AI-supported operating setup that most brands will only have in two years, and you learn to work with it from day one.
  • Two agencies backing you up: Through the ONNI Brands Group, you work directly with One Beyond Search and One AI Commerce and learn from their senior teams.
  • Network instead of bubble: We are a member of the INNER CIRCLE, the entrepreneur mastermind around Johannes Kliesch (Snocks), and other e-commerce communities.
  • Modern Tech Stack: Shopify, Klaviyo, Meta, Klar, Supabase. No legacy tinkering, but tools that are standard today.
  • Flexible Work Model: Hybrid with office days and remote component, flexible working hours, and 30 days of vacation.
  • Fair Package: 49,000 to 59,000 euros gross per year, employee discount on all ONNI brands, modern MacBook setup, and further education budget.
  • Team: Young, ambitious team with a hands-on mentality. We take our work seriously, but not ourselves too much.
