Lifecycle Engineer - AI-Driven Subscription Growth

About the Role

Subsets (YC S23) is an early-stage startup building the future of AI-driven subscription growth. As a Lifecycle Engineer remote, you'll join the early team to work hands-on with our platform and our clients. You will be owning, driving, and expanding adoption of the product across a portfolio of customers while helping to define what great customer outcomes look like as we scale.

What You'll Do

• Work hands-on within the Subsets platform to build, optimize, and iterate on lifecycle campaigns and subscriber journeys alongside our clients.
• Help shape the structure and playbook of the customer team model as one of the first Lifecycle Engineers at Subsets - this is a defining role in how we scale.
• Own and manage a portfolio of 5-10 enterprise customers, acting as the primary point of contact responsible for adoption, business outcomes, and satisfaction of the client.
• Develop a deep understanding of each client's business, proactively identifying opportunities to drive growth and addressing challenges before they arise.
• Partner closely with a solutions engineer, who will handle technical escalations and integrations, so you can stay focused on strategy and outcomes.
• Work in a lean, high-performing team where you will have a significant impact and assume high levels of responsibility.

Requirements

• Hands-on experience in CRM or customer/retention marketing - building journeys, campaigns, and lifecycle strategies inside a platform like Sailthru, Braze, Iterable, or other similar tools.
• Experience being client-facing (e.g., agency or consulting), and ideally with managing relationships at multiple levels.
• Proficiency in email marketing and experience in additional marketing channels (app, on-site, paid social, etc.) is a plus.
• Experience analyzing campaign performance and a basic understanding of running experiments and what good experimental design looks like.
• Experience with subscription businesses and familiarity with terms like ARPU and Lifetime Value is a plus.
• A proactive, big-picture mindset. You're always thinking about where a client relationship is heading, not just the task in front of you.
• A strong bias toward action and the ability to work autonomously in fast-paced, loosely defined environments.
• You prefer a primarily in-office way of working and are energized by the pace and intensity of early-stage startups.

What We Offer

• Competitive salary and equity.
• Company card for all things office food/snacks.
• Great breakfast and lunch (and dinner when working late in the office).
• Relocation support if you don't live in Copenhagen.
