Why Sintra?

50,000+ small business owners use Sintra every day. Not because it's another SaaS tool — but because our AI helpers actually feel like teammates. They reply to customers, post on social media, analyze data, and much more. For someone running a business alone, this is the first time they've had help that actually helps.

We've built something people care about. Now we need to make it great.

Quick summary:

We’re seeking an experienced Copywriter who understands people at a deep level.

You’ll write across ads, funnels, landing pages, and product pages, shaping messages that feel intuitive, honest, and hard to ignore. This role is about connection first and conversion second, because the best-performing copy does both.

You’ll own copy end-to-end, from the first hook to the final CTA, turning complex ideas into simple truths and attention into action.

No bureaucracy.
No layers.
No distance between your ideas and real impact.

You’ll have the freedom to explore, experiment, and take creative risks, and you’ll see the results of your work in real time, used by thousands of real customers.

If you want autonomy, trust, and visible impact every single week, you’ll feel at home here.

What you'll do

  • Write high-performing copy for paid ads, landing pages, and growth funnels

  • Craft hooks, headlines, scripts, and CTAs that feel natural, clear, and persuasive

  • Translate product value into messaging that resonates with real human needs and emotions

  • Collaborate on SEO-driven content by shaping keywords, structure, and messaging, without sacrificing clarity, tone, or conversion.

  • Work closely with creative strategy, media buying, CRO and motion teams to test and iterate

  • Use performance data as feedback doubling down on what works and cutting what doesn’t

  • Take ownership of copy quality and help raise the bar across everything we ship

Who we're looking for

  • Strong experience writing conversion-focused copy, not just brand or awareness content

  • Deep understanding of human psychology, objections, and persuasion fundamentals

  • Proven ability to write ads and pages that make people click, sign up, or buy

  • Sharp understanding of hooks, objections, and simple persuasion

  • Comfortable owning copy end-to-end and working independently

  • Clear, direct writing style - no buzzwords, no filler

  • Enjoys moving fast, testing often, and learning from real data

Salary range: €2,500 - 3,700/ month + meaningful equity - own a part of what you build. (open to negotiation based on experience and fit)

Benefits

  • Equity package: share in the company’s long-term success through an equity plan that rewards your impact and commitment.

  • Flexible working model: enjoy a flexible approach to work that supports a healthy balance between your professional and personal life.

  • Private health insurance: comprehensive private health coverage to support your well-being.

  • Workout sessions with a personal trainer: access guided workout sessions with a personal trainer to help you stay active, healthy, and motivated.

  • Daily office-provided lunch: fresh, complimentary lunch provided in the office every workday to keep you energized and focused.
