About Appstack

At Appstack, we’re reinventing mobile measurement with accurate data, fair pricing, and accessible analytics. Our mission: help mobile apps make smarter, faster growth decisions.

We're building the future of measurement by:

• Democratizing attribution—making powerful analytics affordable and accessible to all apps.

• Prioritizing privacy—by working exclusively with aggregated, privacy-centric data.

• Breaking the mold—challenging the decade-long dominance of legacy MMPs.

The Role

We’re looking for a senior full-stack engineer and technical lead to join us and fully own product development in a fast-paced environment. You’ll work side-by-side with the founders to define the roadmap, lead execution, and ship impactful features quickly—without compromising on long-term scalability.

You’ll also manage and mentor 1–2 other developers, setting the bar for engineering quality, speed, and product thinking. You’ll need to be decisive, fast-moving, pragmatic, and technical enough to confidently lead architectural discussions.

This is a hands-on, high-ownership role with real impact. You'll build, scale, and iterate quickly in the real world.

What You’ll Do

• Own end-to-end delivery of new features and improvements—hands-on and fast.

• Make architecture decisions that scale, with clear tradeoffs and long-term vision.

• Prioritize ruthlessly: balance between fixing bugs, paying off tech debt, and shipping what matters.

• Mentor and guide 1–2 developers, improving team velocity and code quality.

• Collaborate directly with the CEO and CTO to align on product priorities.

• Build and scale data-powered features using our modern analytics stack.

• Contribute to both frontend and backend, and help define our tech roadmap.

Our Stack

• Frontend: Next.js, React, TypeScript, tRPC, Drizzle

• Backend: NeonDB (PostgreSQL), Cube.js

• Infra: Vercel, Google Cloud Platform

What We’re Looking For

• 5+ years of experience in full-stack development with a strong track record of shipping.

• Proven ability to own features end-to-end—from idea to production to iteration.

• Deep knowledge of modern TypeScript, React, and Next.js.

• Strong experience with PostgreSQL (NeonDB or similar) and backend architecture.

• Comfort with API design (tRPC, REST) and modern full-stack patterns.

• Experience with data pipelines, analytics, and visualization (Cube.js, BigQuery, etc.) is a big plus.

• You're a fast shipper with an eye for good engineering tradeoffs.

• Fluent in English

Why Join Us

• Be the technical backbone of a startup with big ambitions.

• Full ownership of your work—from shaping ideas to pushing code.

• Work closely with a small, focused founding team.

• Join us at the early stage and help shape the product, tech, and culture.

Let’s build the next Generation of mobile measurement together.
