    Lemon.io is a marketplace that connects world-class vetted developers with startup teams across the globe. We help our clients hire smarter and move faster, and we’re growing fast doing it.

     

    This role is ideal for someone who thinks like an engineer but operates with deep commercial intuition — you’re not maintaining tools, you’re engineering AI-native growth motions that scale pipeline without scaling headcount.

     

    Why join Lemon.io?

    We’re a bootstrapped, profitable, and growing company that’s all about transparency and impact. Our CEO is hands-on, and our culture is collaborative and open. We operate in a high-velocity sales environment where great ideas thrive, and results matter. As our Founding BDR, you’ll be at the forefront of our expansion, working closely with the CEO and CRO to establish scalable outbound processes. If you’re driven, curious, and ready to grow while building and leading a team once the motion is proven, you’ll fit right in.

     

    What you'll do: 

    • Architect and deploy AI agents (autonomous or multi-agent systems) that handle end-to-end top-of-funnel motions, including prospect identification, account research, intent signal detection, hyper-personalized outreach, lead qualification, and initial engagement across channels (email, LinkedIn, web, chat, etc.).
    • Build and optimize AI-driven workflows for traffic generation and conversion uplift—integrating generative AI, LLMs, and tools (e.g., enrichment platforms, intent data, web scrapers, social listening) to source high-fit ICPs, automate content/messaging creation, and execute multi-step campaigns that boost inbound traffic quality and outbound response rates.
    • Design and implement agentic systems for autonomous prospecting and nurturing: e.g., agents that research companies in real-time, validate ICP fit, generate tailored sequences, book meetings, and hand off qualified leads—aiming for 4–7× conversion improvements and 30%+ faster pipeline velocity compared to manual processes.
    • Own top-of-funnel experimentation and optimization: Run A/B tests on AI-generated messaging, personalization logic, channel mix, and timing; measure impact on key metrics like website traffic quality, form fills, demo bookings, meeting show rates, and early-stage conversion (e.g., visitor-to-lead, lead-to-MQL).
    • Integrate AI across the GTM tech stack (CRM, marketing automation, enrichment/intent tools, analytics) to enable real-time data enrichment, predictive scoring, dynamic segmentation, and automated routing—ensuring clean, intent-rich inputs that feed high-conversion campaigns.
    • Develop custom AI-powered personalization engines that scale one-to-one outreach without manual effort, using generative models to craft context-aware emails, LinkedIn messages, ads, and website experiences that drive higher engagement and conversion.
    • Collaborate with marketing, sales, and product teams to map buyer journeys, diagnose ToFu bottlenecks (e.g., low traffic quality, poor conversion), and prioritize AI use cases that deliver the biggest lifts in pipeline generation and efficiency.
    • Monitor, iterate, and govern AI agent performance: Track agent autonomy, error rates, compliance, output quality, and ROI; refine prompts, guardrails, and orchestration logic to ensure reliable, brand-safe execution and continuous improvement.
    • Build real-time dashboards and attribution models focused on top-of-funnel health: traffic sources, conversion funnels, AI campaign ROI, cost-per-qualified-lead, and predictive signals to guide data-driven decisions and prove AI’s revenue impact.
    • Proactively identify opportunities to replace manual/repetitive ToFu tasks with AI agents, reducing CAC, accelerating time-to-pipeline, and enabling revenue teams to focus on high-value human interactions.
       

     

    What we offer:

    • Startup culture with open communication. Our current eNPS score is 82.
    • Competitive salary in USD
    • Full remote work with flexible working hours
    • 28 working days of vacation a year
    • 7 days of sick leave
    • Annual reimbursements for things that matter to us: health, self-development, travelling, home office upgrade, mental wellness etc.
    • Help with maintaining your Ukrainian PE.
