About the Role 

We’re looking for a Senior Full-Stack Engineer who thrives across the stack and refuses to be boxed in. You move fluidly between frameworks - Next.js to Hono APIs to SvelteKit to Postgres - without friction or hand-holding. AI tools are part of your daily toolkit, and you write specs that make implementation straightforward. 

 

Our Stack 

• Web Frameworks: SvelteKit, Next.js 

• APIs: Hono 

• Mobile: Expo (React Native) 

• Primary Database: Postgres 

• Analytics Database: ClickHouse 

• Languages: TypeScript, Python 

• Infrastructure: Azure, event-driven architecture 

 

Responsibilities 

• Build and ship features across frontend and backend systems 

• Move seamlessly between Next.js, SvelteKit, and Hono depending on what the problem requires 

• Work with Postgres as the primary data layer, designing schemas and optimizing queries 

• Write TypeScript across the stack - React/Svelte on the frontend, Hono/Node.js services on the backend 

• Contribute Python services where appropriate 

• Write technical specifications that define APIs, data models, and UI behavior before coding 

• Use AI-assisted development tools to increase velocity and code quality 

• Collaborate with product and design to translate requirements into working software 

• Participate in code reviews, architecture discussions, and technical planning 

• Improve developer experience through tooling, documentation, and automation 

• *The company reserves the right to add or change duties at any time. 

 

Qualifications 

• 5+ years of professional software engineering experience across frontend and backend 

• Framework fluency - you pick up new frameworks quickly and don’t have strong allegiances; moving from Next.js to SvelteKit to Hono feels natural, not stressful 

• Strong TypeScript proficiency - it’s your primary language 

• Experience with multiple frontend frameworks (React, Svelte, Vue - you’re not married to one) 

• Familiarity with lightweight API frameworks like Hono, Express, or Fastify 

• Deep Postgres experience - you understand indexing, query optimization, and schema design 

• Familiarity with event-driven architectures and message queues 

• Heavy daily use of AI coding assistants - you’ve developed workflows that make you faster 

• Hands-on experience with frontier LLMs beyond surface-level prompting 

• A spec-driven approach - you define what you’re building with precision before you start 

• Experience with Expo/React Native 

• Background with GraphQL, serverless architectures, or ClickHouse
