Responsibilities
Build and maintain secure, scalable web applications using Next.js/React, TypeScript, and Node – backed by PostgreSQL on Supabase (and AWS RDS during migration). Own features end-to-end from UI to database
Design and implement business logic close to the data using Postgres functions, views, triggers, Row-Level Security (RLS), and Supabase Edge Functions, minimizing unnecessary middleware and enabling high performance and strong data isolation
Treat tools like Cursor, Devin, GitHub Copilot, and agent frameworks as core parts of your workflow
Use them to: Scaffold and refactor full-stack features, Generate and evolve schemas, migrations, and RLS policies, Build internal agents that automate repetitive engineering tasks and glue systems together
Embed security best practices into every layer of development — from secure coding and dependency management to data protection and authentication/authorization (Supabase Auth, OAuth2/OIDC, SSO). Collaborate with security researchers to ensure features align with threat models
Work hand-in-hand with product managers and designers to translate customer pain points into impactful, intuitive features
Participate in product discovery and help shape roadmaps with a strong technical and data-informed perspective
Design and optimize API contracts, edge endpoints, and event flows using Next.js (server components, API routes) and Supabase (Edge Functions, real-time)
Consider performance, resiliency, and multi-region deployment (read replicas, data partitioning) as first-class concerns
Model and optimize relational data in PostgreSQL for large, multi-tenant workloads. Own indexing strategies, query performance, and data partitioning approaches to support 10x–30x growth in customers and data
Support automated testing, CI/CD pipelines, database migrations, and vulnerability scanning throughout the development lifecycle
Work closely with infrastructure engineers on Supabase + AWS environments, observability, and performance tuning
Provide guidance and thoughtful code reviews to peers, fostering a culture of quality, security, and ownership
Help raise the bar on full-stack, data-centric, and AI-native engineering practices
Stay ahead of trends in AI-assisted engineering, agentic systems, application security, Next.js, and modern Postgres/Supabase practices, and share what you learn with the team
Qualification
Required
Proven track record building and deploying production-grade applications using Next.js/React and TypeScript, with a strong command of PostgreSQL and at least one backend runtime (Node/TypeScript)
Direct experience with Supabase (Auth, Storage, Edge Functions, RLS, migrations) or a very similar Postgres-based BaaS is a strong plus
You're not just 'familiar' with AI tools — you actively use things like Cursor, Devin, Copilot daily to accelerate implementation and refactors, improve test coverage and docs, explore design alternatives and quickly validate approaches
Strong understanding of secure coding practices, authentication/authorization (OAuth2, OIDC), session management, and vulnerability mitigation in web apps
Deep experience designing relational schemas, optimizing queries, and working on high-volume, multi-tenant Postgres databases
Familiarity with software supply chain risks, SBOMs, CVEs, and vulnerability scanning principles — or a strong interest in learning this domain quickly
You think like a product owner — balancing technical excellence, user experience, and business value
Experience running apps in the cloud, ideally AWS
Familiarity with containers (Docker) and orchestration (Kubernetes) is useful, even if much of the new stack is serverless/managed (Vercel, Supabase, etc.)
Passionate about testing (unit, integration, end-to-end), CI/CD automation, and writing maintainable, well-structured code
Excellent communication skills and experience in cross-functional, remote teams
Preferred
Experience designing or shipping agentic workflows using modern frameworks such as Agno, Vercel AI SDK, or similar (LangChain, LlamaIndex, etc.) for internal tools, customer-facing automation, or developer productivity
Hands-on experience with database administration and performance tuning on Supabase/Postgres — connection pooling, query analysis, indexing strategy, partitioning, and capacity planning
Experience in software supply chain security, SBOM analysis, or vulnerability intelligence
Familiarity with observability tools (Honeycomb, Datadog, Prometheus)
Background in DevSecOps or secure CI/CD pipeline development
Experience contributing to or leading product-focused engineering efforts in cybersecurity startups
Benefits
Competitive Compensation: Salary + equity options.
Comprehensive Benefits: Fully covered medical, dental, and vision.
Flexible Time Off: Unlimited PTO plus generous parental leave.
Remote-First: Work from anywhere in Canada or the United States with a WFH stipend and flexible hours.
