About the role

We're building and scaling a profitable D2C product used by hundreds of thousands of customers globally, processing large volumes of traffic and revenue every month. We're past MVP, battle-tested in production, and now entering a phase of rapid growth and expansion.

We're looking for a strong Full-Stack Engineer who ships fast and independently across the stack β€” someone hungry to grow into senior responsibilities. You'll take ownership of features assigned to you, execute strongly on your own, communicate blockers early, and lean on the team for architectural guidance on more complex decisions.

This is not about maintaining a legacy system. It's about building and scaling real products used by real users β€” fast, and shipping in days, not weeks.

If you're looking for a comfortable 9–5 role, this won't be the right fit. But if you're excited by responsibility, growth, and building high-quality systems in a high-pace environment, read on.

Key Responsibilities

- Build, ship, and iterate on core product features across the stack.

- Take ownership of features assigned to you β€” from implementation through production

rollout and iteration.

- Implement responsive, accessible UIs using TypeScript, TailwindCSS, and established design

systems.

- Work with backend services and APIs, integrating frontend logic with scalable systems.

- Participate actively in code reviews and contribute to maintaining high engineering standards.

- Debug, optimize, and improve production systems in a high-traffic environment.

- Communicate blockers, risks, and progress early and clearly.

- Work closely with Product and the rest of the engineering team to support fast, iterative

delivery.

Qualifications

- 2–4 years of hands-on, production experience building full-stack web applications.

- Practical experience with React and Next.js, including at least 1 year working with the Next.js App Router in production.

- Solid understanding of TypeScript and modern frontend patterns.

- Proven ability to ship features independently β€” from clear requirements to production.

- Experience with PostgreSQL, including basic query optimization and data modeling.

- Working knowledge of caching strategies and performance considerations (Redis or equivalent).

- Strong proficiency with Git, Docker, and modern development workflows.

- Comfortable with CI/CD pipelines and cloud-based environments (AWS, Cloudflare).

- Familiarity with A/B testing frameworks and using analytics to inform decisions.

Ownership & Mindset

- Self-directed executor β€” you ship fast and independently across the stack.

- Take ownership of the features you're working on β€” quality, reliability, and timeline.

- Communicate clearly and proactively β€” flag blockers early, ask questions when needed.

- Hungry to grow β€” you actively seek feedback and want to step up into senior responsibilities.

- High bar for code quality, maintainability, and readability.

- Comfortable working under pressure and navigating ambiguity.

- A pragmatic builder who balances speed with long-term maintainability.

Nice to have

Any combination of the following is a strong signal β€” we'll teach the right person what they don't already know:

- CMS work β€” experience with headless CMS platforms (**Payload preferred**, or Strapi, Sanity, Contentful, or similar).

- Billing & subscription systems β€” exposure to payment or subscription infrastructure (Stripe, Paddle, Recurly, RevenueCat, or similar). Understanding of cancellation flows, retries, and edge cases is a plus.

- Low-level PDF work β€” experience with PDF rendering or manipulation libraries (pdf-lib, PDF.js, PSPDFKit / Nutrient, Apryse, react-pdf). Curiosity about working in close-to-the-metal areas of a PDF viewer or editor.

- Experience with D2C SaaS or subscription-based products.

- Exposure to performance marketing, conversion optimization, or rapid MVP cycles.

- Prior experience with Nest.js or similar Node.js frameworks.

- Open-source contributions, side projects, or a strong GitHub/portfolio.
