[Hiring] Staff Software Engineer, Full-Stack @Faeth Therapeutics

Role Description

We're looking for a Staff Software Engineer to help shape the architecture and technical direction of our core platform. The product is already in motion, and we need someone who can step in, assess what exists, strengthen the foundation, and drive it forward with the quality, security, and performance it demands.

We’re a small, fully remote engineering team (under 20) moving fast. You’ll play a central role in technical decision-making and work alongside experienced engineers to raise the bar across the system. Security and performance aren’t afterthoughts here; they’re core design constraints, and we need someone who treats them that way.

This is an early-stage company. That means you’ll wear many hats. Some weeks you’ll be deep in architecture decisions; other weeks you’ll be debugging a deployment pipeline, reviewing a junior engineer’s PR, or jumping into a customer escalation. If you need tightly defined boundaries, this isn’t the right fit. If you thrive when the scope is wide and the impact is direct, keep reading.

Reports to: Senior Engineering Manager

Location: Remote (India)

Responsibilities

• Own and evolve the architecture.
• Assess the current system, identify what needs to change, and drive the platform’s technical direction - data layer, API surface, frontend application, and deployment infrastructure.
• Build across the stack.
• Write production code daily in React, Node/NestJS, and PostgreSQL on AWS.
• Design for multi-tenancy at scale.
• Solve hard problems around tenant isolation, data partitioning, role-based access, and per-tenant configuration.
• Make security non-negotiable.
• Obsess over performance.
• Build for scale.
• Set the engineering standard.
• Mentor and uplevel.
• Champion modern tooling.
• Stay sharp.
• Wear whatever hat is needed.

Requirements

• 8+ years of professional software engineering experience with a meaningful portion spent in full-stack roles building web applications at scale.
• Experience in high-ambiguity environments.
• Deep proficiency in modern web stacks.
• Proven ability to own system architecture.
• Security-first mindset.
• Performance engineering instincts.
• Strong shipping discipline.
• Enthusiasm for agentic coding and AI-assisted development.
• Bias for ownership and action.

Preferred Requirements

• Experience in healthcare, biotech, or life sciences - particularly with data platforms supporting clinical or research workflows.
• Experience with early-stage or growth-stage companies - building quality infrastructure under constraints, limited resources, shifting priorities, and fast release cycles.
• Experience designing developer-facing APIs or platform primitives consumed by other engineering teams.
• Background in event-driven architectures, CQRS, or domain-driven design.
• Familiarity with infrastructure-as-code (Terraform, CDK, or Pulumi) and CI/CD pipeline design.
• Experience with penetration testing, security audits, or SOC 2 / ISO 27001 compliance processes.
• Track record of evaluating and introducing new tools or frameworks to engineering teams based on measured outcomes.
• Contributions to open source or public technical writing that demonstrate how you think.
