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
