Oxigen

We’re building and scaling a high-volume, performance-driven newsletter portfolio and are looking for a Senior Email Marketing Manager to fully own newsletter growth, engagement, and monetization.

This role is for someone who understands newsletters as a revenue channel, not just a publishing task.

You’ll work closely with authors, AI writers, designers, and monetization partners to ensure every send is optimized for opens, clicks, and revenue, while maintaining strong editorial quality.

Your primary mission:
 

Key Responsibilities

Email & Newsletter Performance Ownership

• Own end-to-end newsletter strategy, publishing, and optimization
• Optimize subject lines, preheaders, layouts, CTAs, and content flow
• Maintain consistent, high-quality publishing schedules across all newsletters
• Review, QA, and approve all outgoing content before sending

 Monetization & Advertising Optimization

• Integrate ads natively within newsletters to maximize CTR and revenue
• Test ad placements, formats, and messaging without harming reader trust
• Analyze performance and continuously improve monetization strategy

Scaling & Team Leadership

• Collaborate closely with writers, AI tools, designers, and growth teams
• Build repeatable processes, guidelines, and quality standards
• Provide weekly performance insights and improvement recommendations
   

Requirements

• Strong experience in email marketing
• Deep understanding of email performance metrics: open rate, CTR, conversions, revenue per send
• Hands-on experience managing multiple email campaings at scale
• Comfortable using AI tools
• Strong editorial and layout instincts (formatting, hierarchy, readability)
• Excellent organization — able to manage 15–20+ newsletters simultaneously
• Strong QA mindset: zero tolerance for broken links, typos, or formatting errors
• High level of English: C1
   

Nice to Have

• Experience with platforms like Beehiiv, Substack, Ghost
• Experience working with ad monetization, sponsorships, or affiliate content
• Background in content-led growth or digital publishing
• Experience scaling multiple content brands or media products

We are hiring on behalf of our client – an American media company with an office in Warsaw. They run a high-volume, performance-driven newsletter portfolio and drive traffic to advertisers and brand partners through owned channels. Affiliate revenue is a core part of the business, and they need someone to own the partner relationships that make it work.

This is a senior, commercial role. You will be the main point of contact for advertisers, affiliate networks, and affiliate managers — building relationships strong enough that partners bring you their best deals first, before anyone else sees them.

You will own payout negotiation end to end: commission rates, CPAs, rev shares, bonuses. That means reading performance data, spotting where a deal is underpriced, and pushing for better terms – not just accepting what a partner offers. You also own tracking hygiene across campaigns: links, sub-IDs, attribution, making sure nothing breaks and no revenue leaks.

Responsibilities

1. Partner communication & coordination

• Be the main point of contact for advertisers, affiliate networks, and affiliate managers
• Keep promo schedules, offer updates, performance feedback, and follow-ups tight and proactive
• Build strong relationships so partners prioritize us and share better deals first
• Spot new opportunities early and move fast to secure them

2. Payout negotiation & deal management

• Negotiate commission rates, CPAs, rev shares, and bonuses to maximize earnings
• Regularly review terms and push for improvements based on performance data
• Identify underperforming/undervalued deals and renegotiate with clear numbers
• Manage renewals and escalate when terms need to change

3. Tracking, links & execution

• Own tracking links, sub-IDs, parameters, and attribution hygiene across campaigns
• Prepare promo packages for internal teams (links, copy, creatives, instructions)
• Coordinate launches across multiple partners and deadlines at the same time
• Keep clean records of partners, offers, assets, and timelines

4. Performance & growth

• Monitor partner performance and flag where we’re leaving money on the table
• Improve partner workflows so we execute faster and capture more revenue
• Longer-term: industry events and conferences can be part of growth, but near-term focus is performance and revenue impact

Requirements

• 4+ years in affiliate / performance marketing (preferably publisher/traffic side)
• Proven experience negotiating payouts (CPA, rev share, commissions, bonuses) with advertisers or networks
• Strong understanding of tracking (links, sub-IDs, attribution, what breaks conversions)
• Highly organized with a “zero mistakes” mindset
• Strong English (C1+)
• Comfortable managing multiple partners and deadlines in parallel
• Hungry to grow, performance-oriented, and comfortable with occasional irregular hours when needed

Nice to have

• Experience with Impact, CJ, ShareASale (or similar platforms)
• Affiliate network relationships / strong partner Rolodex
• Experience in digital media / newsletter monetization
• Comfortable attending industry events

What we offer

• Competitive salary + performance-based bonuses
• 21 paid vacation days + 14 paid sick leaves
• Warsaw office available (hybrid setup)
• A fast-moving, high-performing team with real ownership and growth opportunities

About the project
 

US-founded media company operating email newsletters at scale – millions of subscribers across finance, health, and business verticals. Small engineering team, flat structure, direct ownership, fast iteration. No layers of approval, no large org to navigate.

You'll own the AI layer of the automation platform alongside a counterpart engineer who handles integration and infrastructure.
 

What you'll work on

• AI-driven content generation and management workflows at production scale
• Agent systems coordinating multi-step operational tasks: content, QA, validation, reporting
• RAG pipelines over internal knowledge bases and operational data
• Prompt architectures designed for reliability, cost control, and measurable output quality
• Evaluation and regression testing for LLM systems — "it looked fine when I tested it" isn't good enough
   

Real production systems, not demos. The work removes hours of manual operational work daily and needs to be reliable enough that people actually trust it.
 

Requirements

• 6+ years of development experience
• 4+ years of production Python
• 2+ years shipping production systems with LLMs and agents
• Solid understanding of what happens underneath the frameworks: tokenization, context windows, function calling, when RAG helps and when it doesn't
• Hands-on with agent orchestration: LangChain, LangGraph, MCP, or equivalent
• Clean, maintainable Python – frameworks support your thinking, not replace it
   

Tech stack

Python · FastAPI · PostgreSQL · LLM APIs (OpenAI, Anthropic) · LangChain / LangGraph / MCP · vector databases · Playwright · Docker · proxy infrastructure
 

Conditions

• B2B contract, full-time
• Warsaw office (onsite preferred, remote considered)
• Direct collaboration with technical PM and small senior team

We are hiring on behalf of our client – an American media company. They run a large newsletter operation sending millions of emails a day to cold audiences across finance, health, self-development, and astrology. As the team scales, execution is starting to outpace process – this role exists to fix that.

• Team check-ins and problem-solving reviews
• AI tooling adoption across the team

• 5+ years in project management, running marketing initiatives specifically
• Real marketing fluency – newsletters, paid, social, growth, not just PM theory
• Track record managing several marketing workstreams at once without quality slipping
• Experience building and rolling out PM processes and SOPs for a team
• Daily hands-on AI tool use – you can describe exactly how, this is a hard requirement
• Strong root-cause problem-solving and structured communication
• Ownership mindset – you unblock things yourself, no hand-holding
• C1+ written and spoken English
• Ready to grow into a leadership role as the team scales
   

Nice to have

• Background in newsletter, media, affiliate, or performance marketing
• Hands-on campaign experience, not just managing people who ran campaigns
• Make, Zapier, or similar automation tools
• Notion, ClickUp, Asana, or Airtable
• Experience with email platforms or audience growth metrics
• Experience working with designers, writers, or QA teams
   

Compensation and benefits

• Competitive salary + bonuses
• 21 paid vacation days, 14 paid sick days
• Remote-first team
• Corporate library, team activities
