Senior Full -Stack Engineer (Remote USA)
CalliereThis is a remote position.
We are building a category-defining platform that operates at scale and demands high engineering rigor. The product sits at the intersection of real-time data, complex systems, and critical user workflowsâwhere performance, reliability, and clarity are non-negotiable.
We are hiring a Senior Full-Stack Engineer who wants to operate in a high-trust, high-ownership environment. This is not a role for someone looking to simply execute ticketsâyou will be expected to take problems from ambiguity to production, influence technical direction within your domain, and ship systems that matter.
You will work across the stack, with a strong focus on backend architecture and API design, while maintaining a sharp eye for product quality and user experience.
What Youâll Own
Architect and deliver scalable systems and APIs that power core product functionality.
Take full ownership of features, from problem definition through design, implementation, and iteration.
Drive technical decisions within your scope, balancing speed, quality, and long-term maintainability.
Partner directly with product and business stakeholders to shape solutionsânot just implement them.
Build shared infrastructure and services used across multiple teams.
Raise the bar on code quality, system design, and engineering standards.
Requirements
What Sets You Apart
You have built and operated systems that handle real scale and complexity.
You think in systems, not just components, and understand trade-offs deeply.
You are product-orientedâyou care about why something is being built, not just how.
You bring a strong sense of ownership and are comfortable operating with incomplete information.
You communicate clearly and push for clarity when things are ambiguous.
You elevate the team through your execution, judgment, and collaboration.
Environment
The team is composed of high-performing engineers who are trusted to lead within their scope. There is minimal bureaucracy and a strong bias toward action.
Work is structured in short cycles, but expectations are outcome-driven, not process-driven. Engineers are expected to step up, take initiative, and deliver meaningful results.
The team is distributed across North America with a consistent daily overlap window for collaboration.
An on-call rotation (~every 4â6 weeks) is part of the role, covering both system alerts and internal support channels.
Stack
Frontend: React, TypeScript
Backend: TypeScript (primary), with Python and Go in the ecosystem
Systems: Distributed, service-oriented architecture
Data: PostgreSQL and large-scale analytical systems; strong data modeling expected
Infrastructure: GCP, CI/CD pipelines, containers; Kubernetes is a plus
