Staff Engineer, Member Lifecycle

As our new Staff Engineer for the Member Lifecycle (MLC) domain, you will set the long-term technical direction for how Vinted reaches, grows and talks to its members. MLC owns three core areas, and the systems behind them are used by teams across Vinted:

• Member Engagement and Communication: the communication platform and orchestration behind billions of messages a month across email, push, inbox notifications and in-app touch points, plus our in-house Vinted CRM, consent management and our Braze integration.
• New Member Acquisition: referrals, SEO and GEO, the digital tracking stack, and the technology behind marketing and country launches.
• General Vinted Content Capabilities: localisation of the Vinted platform, and the dynamic content translation that other teams and systems rely on.

Your primary focus will be the end-to-end architecture of our communication ecosystem: how messages are orchestrated, ranked, rendered, delivered and measured, and how our in-house tools and Braze fit together. Alongside this, you will shape the technical direction across acquisition and content, so MLC grows as one coherent set of platforms rather than a collection of separate services.

Reporting to the Director of Engineering for Member Lifecycle, you will work closely with Engineering Managers, Product and Data Science in the domain, and with Staff Engineers across Marketplace and Platform, to align technical direction and raise the engineering bar.

In this position, you’ll

• Own the long-term technical vision for MLC, starting with the communication ecosystem: the communication platform and orchestration, Vinted CRM, consent management and the Braze integration
• Define an end-to-end architecture for how messages are targeted, ranked, rendered, delivered and measured, so every team at Vinted can reach members without adding noise
• Help engineers in the domain prepare strong RFCs: frame the problem, compare the options, and bring in the right reviewers early
• Lead the move from static send rules to smarter delivery, working with data scientists in the domain to take communication ranking from proof of concept to production
• Draw the line between our in-house tools and Braze: decide what each should own, guide build-versus-buy decisions, and define how data, consent and localisation flow between them
• Drive the modernisation of legacy parts of the domain
• Guide the technical direction for acquisition and content: trusted tracking data, SEO and GEO foundations, and a translation platform that uses automation and AI where they improve speed and quality
• Set engineering standards across the domain for APIs, data contracts, observability, privacy and reliability
• Lead high-impact cross-team technical initiatives and report on them transparently: flag risk early with a dated path to green
• Turn unclear situations into proposals: frame the options, recommend one, and get a decision with a date
• Represent MLC within the Staff / Principal Engineer layer, helping steer technical priorities and architectural trade-offs across Vinted.

• Prior experience as a staff or principal engineer, architect, or lead engineer, delivering cross-team platform initiatives in organisations operating at scale
• Strong architectural judgement in distributed, high-throughput systems, and the ability to connect technical decisions to product and business outcomes
• You can create a technical vision in an ambiguous environment and turn it into clear architecture, standards and execution direction across several teams
• You bring proposals, not just problems, and you’re comfortable pushing for decisions
• You review and approve RFCs written by engineers in the domain, and take responsibility for the technical decisions they lead to
• You delegate refinement and implementation to engineers while staying close enough to the architecture to give meaningful guidance
• A data-driven approach: experiments, metrics, and working with analysts or data scientists
• You’re comfortable working with AI, in your own work and in the systems you build, and know where it helps and where it doesn’t
• Clear communication with engineers, product, leadership and external partners, in writing and in person, in excellent English
• Strong stakeholder management: you build alignment across teams and domains, and influence without authority
• Flexible and adaptable when priorities change
• Experience with large-scale messaging or notification systems, CRM or marketing automation platforms (such as Braze), consent management, localisation or SEO is a strong advantage.

• The opportunity to benefit from our share options programme
• 25 working days of holiday
• Access to all the tools & tech needed for work
• Home office support: we provide IT workstation equipment and a personal budget of up to 540 for home workplace furniture
• Private health insurance
