ONER ACTIVE Role Systems Administrator Reports into Systems Manager Contract Type Full Time, working 7.5 hours per day, 5 days per week Location Hybrid, working 3 days a week in our offices based in Old Street, London.
About You
As Operations Systems Engineer at Oner Active, you will shape how our technology stack runs as we scale to a £500m global omnichannel brand. You will own the day to day health, automation, and documentation of our core operational systems. That includes NetSuite ERP, Shopify (B2C), Teamwork Commerce (POS), eCom360 (Proprietary Middleware), 3PL and WMS integrations, and Narvar for returns.
The role is built around three principles:
- Automate anything that should not need a human.
- Document everything so both people and AI agents can use it.
- Bridge between our operational teams and our external technical partners.
As we open our US Distribution Centre, launch US retail, and complete the NetSuite ERP implementation, you will own end to end testing of new features and integration health across the stack. Once stable, you will keep finding ways to remove friction and unlock the teams that use these tools every day.
What we are looking for
You will be the internal subject matter expert for workflows that touch NetSuite, Shopify, Teamwork, the 3PL, or eCom360. People will come to you first when they see something is incorrect, or want to explore ways to make a process easier. You will act as the translator between non-technical teams (Merchandising, Ops, Finance, Digital, Retail) in the UK and our external technical partners (the SUG team in Austria, CMG for NetSuite). You will write the briefs, agree the specs, and make sure both sides land on the same outcome.
You will own automation as a discipline, not as a side project. Where the same manual task happens twice, you will build something to remove it. You will use modern tooling to connect systems, route exceptions, and resolve common integration failures without human intervention. You will use AI as a daily tool. That means drafting NetSuite Saved Searches with AI assistance, writing tech specs faster, generating test cases and synthetic data for UAT, and building small internal tools yourself rather than waiting on external developers.
You will manage end to end testing (SIT and UAT) of new features, including the US 3PL integration, Shopify POS retail rollout, and NetSuite ERP go-live. You will build and maintain a modern knowledge base. SOPs that are queryable by AI, Loom videos for any process with a UI, and structured documentation that both operators and future AI agents can use.
You will configure systems natively where possible: Saved Searches, custom fields, UI tweaks, dashboards, workflows. Routine configuration should not need an external ticket. You will provide data and reporting support to Finance and Merchandising. Accurate actuals, dashboards, and ad hoc analysis. AI accelerates this work but does not replace your judgement on it.
What you will need
- 3 to 5 years in a Tech, Systems, or Internal Tools role at a high-growth e-commerce or DTC business.
- Strong hands-on experience with Shopify, NetSuite ERP, POS and 3PL integrations.
- Experience with middleware or integration platforms.
- Working alongside bespoke routing tools is a major plus.
- Demonstrable AI fluency.
- Hands-on experience building automations in n8n, Make, Zapier, or equivalent.
- A bias to build.
- Experience producing AI-queryable documentation and modern knowledge bases in Notion, Loom, or similar.
- Ability to give clear and regular updates to leadership.
- Confident writing technical specifications and acting as the bridge between developers and operators.
- Experience supporting complex project delivery: system implementations, feature releases, and product enhancements.
- Confident as an internal trainer, so operational staff can do their work without bottlenecking on you.
Responsibilities
- Business analysis, requirement definition, and technical scoping for new operational requests.
- Defining operational process flows and mapping data flows across Shopify, eCom360, NetSuite, 3PL, and Teamwork.
- Writing technical specifications and managing the brief between third party partners (SUG, CMG) and internal stakeholders.
- Owning the automation roadmap.
- Building, maintaining, and monitoring automations that remove recurring manual work.
- Designing and maintaining the AI-queryable knowledge base used by both humans and future agents.
- System Integration Testing (SIT) and User Acceptance Testing (UAT) for major rollouts, including Retail POS, the US DC, and NetSuite.
- Cutover and go-live management.
- Post go-live hypercare and integration health monitoring.
- The goal is fewer manual interventions over time, not more.
- Native system configuration in NetSuite, Shopify, Teamwork, and the PIM.
- Internal training and onboarding so teams can operate the systems day to day.
Benefits
- 25 days annual leave plus bank holidays and work from anywhere up to 4 weeks a year.
- 5% employer match salary sacrifice pension scheme.
- Generous Oner Active discount plus regular office sample sales.
- Free Evolve You subscription.
- Private Healthcare with Vitality including optical and dental.
- Monthly wellness allowance and team workout classes.
- Start-up culture, the chance to learn and make a real impact.
- Great employee events like our Summer party, Christmas party and team away days.
- Healthy office snacks and fruit (plus a chocolate cupboard for a sweet treat for the balance).
- Dog friendly office.
