About the Role 

We’re hiring a Staff Engineer to operate as a technical force multiplier across the organization. You’ll tackle the hardest problems, set architectural direction, and raise the bar for engineering quality. This role dances between all layers of the stack—dashboards, mobile, AI, workflow orchestration, and infrastructure. You’re a generalist who goes deep when needed, and you’ve fully embraced AI-assisted development as a way to amplify your impact. 

 

Our Stack 

• Dashboards & Web: SvelteKit 

• Mobile: Expo (React Native) 

• AI Orchestration: Mastra 

• Workflow Orchestration: Inngest 

• Backend & Auth: Supabase 

• Primary Database: Postgres 

• Analytics Database: ClickHouse 

• Languages: TypeScript, Python 

• Infrastructure: Azure, event-driven architecture 

 

Responsibilities 

• Drive technical strategy and architectural decisions across multiple teams and stack layers 

• Solve ambiguous, cross-cutting problems that span dashboards, mobile, AI, and backend services 

• Build and extend SvelteKit dashboards that power internal and external tooling 

• Contribute to our Expo mobile applications when needed 

• Design and implement AI-powered features using Mastra 

• Architect reliable workflows and background jobs with Inngest 

• Work across our Supabase backend, Postgres, and ClickHouse data layers 

• Define and champion spec-driven development practices organization-wide 

• Write code, review code, and mentor engineers at all levels 

• Evaluate and integrate AI tools that accelerate engineering velocity 

• Partner with leadership on technical roadmap and build-vs-buy decisions 

• Establish patterns, libraries, and frameworks that other engineers build on 

• Experience with SvelteKit in production 

• Background with Supabase (auth, realtime, edge functions) 

• Familiarity with Inngest or similar event-driven workflow systems 

• Experience with distributed systems, event-driven architecture, or real-time applications 

• Background mentoring or managing engineers 

• History of open-source contributions or public technical writing 

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

 

Qualifications 

• 8+ years of software engineering experience with demonstrated technical leadership 

• Broad technical fluency - you context-switch fluidly between web (SvelteKit/React), mobile (Expo), backend (Supabase, Node.js, Python), and infrastructure 

• Strong TypeScript proficiency across the full stack 

• Experience with workflow orchestration tools (Inngest, Temporal, or similar) 

• Familiarity with AI/LLM orchestration frameworks - Mastra experience a plus, but we value adaptability 

• Deep Postgres expertise and familiarity with analytical databases like ClickHouse 

• Experience designing systems that scale in complexity and traffic 

• Deep, practical use of AI coding tools integrated into your development process 

• Significant experience with frontier LLMs - you’ve pushed beyond basic use cases into advanced workflows 

• Strong written communication - you write specs, RFCs, and documentation that drive alignment 

• A track record of improving engineering culture and practices at previous organizations 

 

Skills 

• Relentlessly curious - you dig into new tools and technologies before they have comprehensive documentation 

• High agency - you don’t wait for permission or detailed instructions; you figure things out and drive forward 

• Comfortable with ambiguity - you can pick up bleeding-edge LLM tools and make them productive without hand-holding 

• A true generalist - you don’t identify as “a frontend engineer” or “a backend engineer”; you’re just an engineer 

• Self-directed - you identify what needs to be done and do it
