About the client:

Our customer is the European online car market, with over 30 million monthly users and a presence in 18 countries. As a Lead FullStack Engineer, you will play a pivotal role in shaping the future of online car markets and enhancing the user experience for millions of car buyers and sellers.

About the role:

We’re looking for a Senior Software Engineer who takes end-to-end ownership, thrives in ambiguity, and wants to build systems that matter. This role is central to rethinking and rebuilding our clients’ auto repossession and remarketing platform, a system that directly influences how vehicles are recovered, processed, and remarketed across the big automotive ecosystem. This is an AI-first engineering role—not in name, but in practice. You’ll continuously evaluate where AI (including LLMs and agentic tools) can meaningfully improve engineering velocity, system quality, and operational efficiency, while applying strong judgment about where it should not be used.

You’ll help shape architecture, influence technical direction, and own what you build—from design to production. 

What You’ll Do:

Build & Evolve Critical Systems

Rethink and reshape core workflows based on a deep understanding of auto repossession and remarketing processes.

Design and implement scalable, resilient systems using modern architectural principles: clear service boundaries, modularity, and observability.

Incorporate LLMs and AI-driven components to improve data validation, document processing, and operational decision-making.

• Use AI-assisted and agentic coding tools to accelerate development—while maintaining high standards for correctness, security, and maintainability.

Own Architecture & Technical Decisions

Drive architectural discussions and decisions, balancing pragmatism with technical excellence.

• Set and enforce high-quality bars for new services and modules, with a focus on testability, performance, and reliability.
• Identify and reduce technical debt in ways that measurably improve developer velocity and system robustness.

Build With an Ownership Mindset

Work across the full software lifecycle: design, build, deploy, operate, and iterate.

• Embrace a “you build it, you own it” DevOps mindset alongside your team.
• Make thoughtful trade-offs between effort, quality, and user value—always with accountability for outcomes.

Collaborate & Lead

• Work closely with product managers, designers, and other engineers in an agile, cross-functional team.
• Contribute ideas, challenge assumptions, and continuously improve how we build software.
• Mentor and support other engineers through code reviews, design discussions, and technical leadership.

What We’re Looking For:

• Canadian timezone work hours
• A Lead (7+ years of experience) engineer who owns results, not just implementations.
• Someone who enjoys complex problem-solving and isn’t afraid of legacy systems—or changing them.
• Strong engineering fundamentals: clean code, testing discipline, system design, and performance awareness.
• Strong experience with TypeScript and modern React / Next.js
• Strong experience building production systems with .NET (Core / modern .NET preferred).
• Strong experience building production systems with C#
• Comfort operating in production environments and learning from real-world feedback.
• A builder’s mindset: If you can think it, you can build it. If you build it, you own it.
• Experience leveraging AI, Generative AI (GenAI) to enhance engineering productivity, automate repetitive tasks, and optimize workflows. You should demonstrate the ability to integrate AI-driven solutions into your daily work — such as code generation, debugging, reviews, documentation, and decision support—to improve efficiency for yourself and your teams. A proactive approach to exploring and implementing AI tools that drive innovation and streamline development processes is highly valued. (Strong must)

Remote or Warsaw  |  Full-time

We are building and scaling a high-volume, performance-driven newsletter portfolio and we are looking for a Senior Email Marketing Manager to fully own newsletter growth, engagement, retention, and monetization. This is a role for someone who understands newsletters as a revenue channel, not just a publishing task — and who is driven to make ours the best in their categories, beating every competitor on engagement and quality.

You will work closely with writers and designers to ensure every send is optimized for opens, clicks, retention, and revenue while maintaining strong editorial quality. You will also own the part of this that most people get wrong: deliverability. 

Your primary mission: own 7 to 10 newsletters to start, drive their engagement and retention to best-in-class levels, and scale the portfolio beyond that as you prove the model. This is an IC role with room to build a team around you as the portfolio grows. We are looking for a proactive contributor who is comfortable pushing the limits — someone who is not satisfied matching the competition but determined to beat it. If you treat email as a growth engine and you have the deliverability chops to protect it at scale, this role was built for you.

WHAT YOU WILL OWN

Engagement, retention, and newsletter performance

• Own engagement and retention as the primary KPIs of the role — opens, clicks, and active subscriber rates are what you live and die by
• Own end-to-end newsletter strategy, publishing, and optimization across the full portfolio, starting with 7 to 10 properties
• Relentlessly find new ways to make our newsletters the best in their categories — study what competitors do, then do it better, and find the angles they have not thought of
• Optimize subject lines, preheaders, layouts, CTAs, and content flow against engagement, retention, and revenue
• Build and run retention programs that keep subscribers active and reduce churn over the full subscriber lifecycle
• Maintain consistent, high-quality publishing schedules across every newsletter — nothing slips, nothing goes out late
• Review, QA, and approve all outgoing content before it sends — zero tolerance for broken links, typos, or formatting errors

Deliverability and sender reputation

• Own deliverability end to end — inbox placement, sender scores, bounce management, and domain health across all sending infrastructure
• Monitor deliverability at the ISP level: know the rules and thresholds of each major provider, watch complaint rates independently per ISP, and pause or throttle sends by ISP when the data demands it
• Manage sending domains, IP pools, warm-up schedules, and authentication (SPF, DKIM, DMARC) with precision — no cowboy sends, no shortcuts
• Diagnose and resolve deliverability issues yourself before they become crises — authentication failures, spam trap exposure, blacklisting, FBL complaints — without deferring to platform support
• Use engagement data to protect inbox placement: know when to use openers versus clickers, how to manage sending to engaged versus dormant segments, and how to keep reputation strong across a high-volume portfolio
• Stay ahead of inbox provider algorithm changes and compliance shifts that affect delivery
• Where cold email is used for growth or partnerships, keep it on completely separate infrastructure from newsletter sending — protecting warm deliverability is non-negotiable

List health and hygiene

• Own list quality as a strategic asset across all properties — suppression management, re-engagement campaigns, sunset policies, and ongoing hygiene
• Design and execute re-engagement programs that recover dormant subscribers without damaging sender reputation in the process
• Build segmentation logic that ensures the right messages reach the right subscribers at the right time
• Set clear quality thresholds for subscriber health and act on them — know when to clean and have the discipline to do it

Monetization and advertising

• Integrate ads natively within newsletters to maximize CTR and revenue without harming reader trust
• Test ad placements, formats, and messaging continuously — and know exactly where the line is between revenue and reader fatigue
• Analyze monetization performance across the portfolio and continuously improve the strategy based on what the data shows
• Work closely with monetization partners to package inventory and report performance accurately and credibly
• Track revenue per send and revenue per subscriber as core metrics, not afterthoughts

Growth, experimentation, and best-in-class quality

• Proactively push the limits of what the newsletters can do — test new formats, content angles, engagement mechanics, and growth tactics that competitors are not trying
• Develop and test non-standard engagement formats — polls, surveys, interactive elements, reader feedback loops — and measure their impact on retention and list health
• Benchmark against the best newsletters in each category and set the standard higher — the goal is to be the best, not to keep pace
• Treat every send as a performance event: measure it, learn from it, and feed the insight back into the next one
• Bring ideas to the table without being asked — this role rewards initiative and punishes passivity

Editorial standards and compliance

• Own editorial and content-standards compliance across the portfolio — ensure every send meets the quality, accuracy, and brand standards expected of a best-in-class newsletter
• Maintain consistent editorial guidelines across all properties and enforce them as the portfolio scales
• Catch content issues — factual, tonal, formatting, or brand — before they ship, not after

Scaling, processes, and collaboration

• Collaborate closely with writers and designers to keep the portfolio publishing at a high standard
• Build repeatable processes, guidelines, and quality standards that let the operation scale beyond the initial 7 to 10 newsletters without quality slipping
• Use AI tools to accelerate content production, QA, and analysis across a high volume of sends
• Provide weekly performance insights and clear, actionable improvement recommendations
• As the portfolio scales, build and lead a team to support it — setting standards and maintaining quality across everyone's output

WHAT WE ARE LOOKING FOR

Must-have

• Strong experience in email marketing with direct ownership of high-volume programs — managing multiple lists or newsletters simultaneously is a requirement, not a bonus
• Deep understanding of email performance metrics: open rate, CTR, retention, conversions, and revenue per send — with engagement and retention as the metrics you optimize for above all
• A proven drive to grow newsletters and beat the competition — examples of taking a property and measurably improving its engagement, retention, or growth
• Hands-on deliverability expertise: ISP-level complaint monitoring, IP and domain warm-up, authentication, and inbox placement troubleshooting — strong critical thinking applied to data, not surface-level familiarity
• Proven experience managing multiple email campaigns at scale without quality slipping
• Some cold email experience, with the discipline to keep cold infrastructure separate from newsletter sending
• Comfortable using AI tools as part of daily production and analysis workflows
• Strong editorial and layout instincts — formatting, hierarchy, readability — you know what a good send looks like and you can spot what is wrong fast
• Excellent organization: able to manage 7 to 10 newsletters from day one and scale well beyond that without dropping a single one
• Strong QA mindset with zero tolerance for broken links, typos, or formatting errors
• Excellent English, written and verbal (C1 or above)

Nice to have

• Experience with ad monetization, sponsorships, or affiliate content
• Experience with platforms like Substack or Ghost
• Background in content-led growth or digital publishing
• Experience scaling multiple content brands or media products
• Familiarity with list validation services such as NeverBounce, ZeroBounce, or similar

WHO FITS THIS ROLE

You treat email marketing as a growth and revenue engine, not a publishing chore. You are not satisfied being good — you want our newsletters to be the best in their categories, and you are the kind of person who studies the competition specifically so you can beat them. Engagement and retention are the numbers you obsess over, because you know they are what separate a newsletter that compounds from one that slowly dies.

KEY COMPETENCIES

Engagement and retention  |  Deliverability and sender reputation  |  Newsletter growth  |  Monetization and advertising  |  Editorial standards and compliance  |  QA discipline  |  Proactive experimentation
