Leadtech Group

• Design, implement, and optimize waterfalls on mediation platforms (AppLovin MAX, IronSource/Unity LevelPlay, AdMob / Google Ad Manager). • Configure and manage dynamic floor prices and real-time bidding (in-app bidding) to maximize eCPM. • Evaluate and onboard new ad networks and programmatic demand. • Monitor key KPIs: eCPM, fill rate, ARPDAU, ad revenue per session, impression share. • Run cohort analyses and A/B tests on ad formats, frequencies, and integrations. • Identify data-driven improvement opportunities using BI tools (Looker, BigQuery, Amplitude). • Define the ad format strategy per app: interstitials, rewarded, banners, native, MREC. • Ensure the right balance between ad monetization and user experience, reducing ad-induced churn. • Collaborate with Product to properly integrate ad placements into the user flow. • Manage relationships with ad networks (Meta Audience Network, AppLovin, IronSource, Mintegral, Vungle, InMobi, etc.). • Negotiate guaranteed deals and header bidding arrangements with strategic partners. • Stay up to date on programmatic market trends and policy changes (ATT, privacy). • Ensure compliance with App Store, Google Play, and individual ad network policies and guidelines. • Implement brand safety measures, ad quality filters, and advertising inventory review processes.

• Develop and maintain features on our Next.js (App Router) frontend using TypeScript, SWR, Tailwind, and a component-driven design system, with full internationalization (i18n) support. • Design, implement, and maintain RESTful APIs with NestJS (TypeScript) to manage authentication, data processing, billing, usage tracking, and orchestration of AI workflows. • Own backend services end-to-end: from schema design and migrations to deployment and observability, and contribute to new services as the product surface grows. • Integrate and maintain third-party SDKs and APIs that power critical product flows, including payment processing, authentication, analytics, and messaging. • Build AI agents and tools using the Claude SDK and Model Context Protocol (MCP): giving LLMs real-time access to data, APIs, and tools so they can take meaningful actions on behalf of users. • Contribute to schema design with Prisma and PostgreSQL, write and review migrations, and reason carefully about data models that evolve safely over time. • Implement and maintain feature flags, A/B experiments, and analytics events so product decisions are driven by data. • Handle incoming webhooks and asynchronous task processing with the rigor required for payment-critical and PII-handling code paths (idempotency, retries, fault tolerance). • Collaborate with AI product managers and AI specialists to translate complex requirements into robust, scalable features — and push back on complexity when a simpler path exists. • Collaborate on application deployment and help maintain our cloud infrastructure.

• Design and build multi-agent AI systems integrating LLMs for end-to-end customer-facing workflows: email triage, refund processing, escalation logic, voice bot interactions. • Develop and maintain N8N automation workflows. Mid knowledge of python and javascript are required for code node scripting. • Integrate voice AI platforms (e.g. Retell AI, ElevenLabs, ConnexAI, Vapi, BlindAI, etc.) with custom prompt logic for call bot behaviour, customer handling, and multi-step flows. • Classify and prioritize automation use cases based on business impact, technical complexity, and urgency. • Ensure every automated workflow reflects high-quality communication standards, SLA adherence, tone consistency, and operational resilience. • Define, document, and test REST APIs for integration with CRMs, helpdesk platforms (Freshdesk), and internal systems across multiple product versions. • Perform initial technical assessments of integration issues by reviewing API responses, logs, configurations, and system outputs to detect errors or inconsistencies. • Build and manage comprehensive API test suites in Postman and N8N, covering edge cases and structured regression scenarios. • Collaborate with Development, Product, and QA teams to reproduce, diagnose, and escalate complex technical issues efficiently and with complete context. • Participate in regular syncs with technical leads to identify recurring automation gaps and drive process improvements. • Craft and iterate on LLM prompts for structured output generation — including JSON schema enforcement, multi-category classification, sentiment analysis, and application reference extraction. • Debug and improve AI pipeline outputs, addressing inconsistencies in model responses. • Apply knowledge of AI delegation and orchestration patterns to design reliable, scalable agent workflows. • Identify recurring workflow gaps or automation opportunities and propose preventive or optimisation actions. • Contribute to internal technical documentation, API specs, runbooks, and workflow guides to improve team efficiency and knowledge sharing. • Support onboarding and upskilling of new team members on automation tools, AI systems, and integration patterns. • Collaborate with cross-functional teams on initiatives that enhance the customer experience and streamline operational workflows.

• Provide legal advice and support for existing business models (website and apps) as well as new ones. • Managing legal and compliance matters to ensure the achievement of commercial objectives while minimizing risks. • Ensure compliance with applicable laws and regulations. Prepare and review NDA’s, agreements, legal texts as well as other documents to help and support the business growth and expansion. • Proven experience in the design and implementation of compliance and ethics frameworks, including internal reporting channels (whistleblowing), codes of conduct and training programs, able to advise, oversee and quality-check these processes within the organization. • Ensure through cooperation with the Security team the proper compliance in terms of data protection and privacy (GDPR, LSSI, LOPGDDD, RIA). • Lead the development and enforcement of internal compliance policies, risk assessments and ethics guidelines aligned with regulatory requirements. • Collaborate in the process of trademark registration of the different projects of the company and ensure compliance with Intellectual Property and legal defense of the company's rights. • Ensure adequate response to inquiries from regulatory authorities and/or third parties concerning the Company’s operation in different market niches.

• We're looking for a Senior Product Owner with real experience in digital ecommerce products and direct ownership over the payments and checkout area. • This is not a "ticket manager" role. We want someone who understands the business, challenges assumptions, speaks engineering's language without losing sight of the user, and knows that behind every lost conversion point in checkout there's a product decision that was (or wasn't) made correctly. • One more thing: we don't care what you studied 🎓. Journalism, Business, a Web Dev bootcamp, Philosophy… degrees are fine, but what matters here is what you can do, how you think, and what you've delivered.
