We are looking for a Head of Performance Marketing & Growth who will own the full growth engine - and drive it to scale.

This is not a "manage the metrics" kind of role. You're coming in at an active growth stage where the foundation exists - but the system needs a strong hand to scale.
Your mission: build a systematic Paid Social-first growth engine, close the loop between creative, acquisition, onboarding, and paywall - and make unit economics actually work on iOS subscription products (weekly/annual plans, trials, paywall optimization, LTV-driven economics).

You'll operate with high ownership, speed, and direct access to the CEO. This role is ideal for a UA leader whose core is mobile acquisition - and who is ready to go beyond the channel: own business outcomes, drive product and creative teams, and think in systems, not campaigns.

What You'll Own

• Full growth cycle: acquisition → ASO → onboarding → paywall
• Paid Social-first strategy with focus on Meta scaling and TikTok as a growth lever
• Creative performance as a key growth lever - strategic ownership of the creative pipeline: angles, formats, win rate, iteration velocity
• ROAS, unit economics, and P&L accountability - you're responsible for the number, not just the channel
• Building and leading a team across UA, growth, and creative coordination
• Cross-functional sync with Product, Analytics, Monetization, ASO, and Creative teams
• Defining and evolving the monetization strategy together with Product: paywalls, pricing, trial mechanics
• Direct partnership with the CEO - strategy alignment, fast decisions, no bureaucracy

Your First 3–6 Months

• Full audit: traffic sources, unit economics, creative performance, funnel conversion
• Define and launch a Paid Social growth strategy - from hypothesis to execution
• Strengthen the analytics and attribution setup - ensure the team can make confident scaling decisions based on data
• Rebuild the creative testing system if needed: win rate, velocity, feedback loop with the creative team
• Build a roadmap to traffic profitability within 6–8 months
• Set up a structured marketing - product interaction process
• Assess, structure, and stabilize the team - identify gaps, close them

What Success Looks Like

• Systematic growth appears in Meta and TikTok - not one-off wins that can't be repeated
• The creative → acquisition → onboarding → paywall loop starts working as one connected system
• Analytics delivers the numbers you need to make decisions - not the other way around
• The team has a clear leader who sets direction, removes blockers, and raises the bar

What We're Looking For

Hard requirements:

• 5+ years in B2C Mobile User Acquisition or Performance Marketing
• 2+ years in a leadership role with direct ownership over results - not just managing people, but owning numbers
• Proven track record scaling Paid Social on iOS subscription apps with significant budgets
• Deep understanding of unit economics and P&L management
• Strong command of the subscription funnel: install → trial → paid → retention levers
• Ability to connect creatives, funnels, and analytics into one coherent growth system
• Experience building and managing teams, including hiring and letting go

The kind of person who fits:

• You don't run campaigns yourself anymore - but you could. And your team knows it
• You think in systems, not tasks. You don't just solve problems - you build the structure that prevents them
• You own results. Not the process, not the effort - the outcome
• When something is unclear, you don't wait for direction. You define it
• You're equally comfortable building from zero and scaling what works - sometimes at the same time
• You push things forward. Across teams, through blockers, past excuses.

• Observability & Evaluation: Implement automated evaluation pipelines using LangSmith. You will be responsible for setting up regression testing for prompts and agents to measure quality (correctness, faithfulness) before deployment.
• Advanced RAG: Refine retrieval strategies. Work on hybrid search implementation (Keyword + Vector), re-ranking, and query expansion to feed the most relevant context to the model.

Requirements

• Python Expert: Strong proficiency in modern Python. Deep understanding of asynchronous programming (asyncio) patterns is mandatory, as our entire I/O pipeline (Network, DB, LLM) is non-blocking. Experience with FastAPI and Pydantic (v2).
• Agentic Frameworks: Production experience with LangChain. Hands-on experience or deep conceptual understanding of LangGraph (or similar state-machine-based agent frameworks).

Deep LLM Expertise (What we mean by "Deep"):

• Non-determinism Management: Strategies for handling LLM hallucinations and ensuring reliable outputs (e.g., self-correction loops, specific prompting techniques like CoT/ReAct).
• Structured Outputs: Experience forcing LLMs to adhere to strict schemas (Pydantic/JSON mode) for reliable downstream processing.
• Context Optimization: Advanced strategies for managing limited context windows (summarization chains, sliding windows, selective context injection) beyond simple truncation.
• Inference Economics: Understanding the trade-offs between model size, latency, and cost (e.g., when to route to GPT-4 vs. a smaller/faster model).

Nice to Have

• Experience with Elasticsearch (DSL queries, analyzers).
• Knowledge of vector databases and embedding models.
• Background in FinTech or familiarity with financial data structures.
