HireNow Staffing is actively recruiting a seasoned, highly skilled Staff Full Stack Engineer to join one of our valued client partners. HireNow Staffing is acting as a direct placement partner for this senior-level full stack engineering role. Only candidates who fully meet the required qualifications and demonstrate a stable, progressive career history will be considered for interview.

Position Overview

This is a foundational engineering role within a fast-scaling software startup building advanced operational software in a complex, real-time environment. The selected engineer will operate at a staff level—owning architecture, shaping engineering direction, and delivering production-grade systems end to end.

This position requires deep technical capability across backend systems, frontend architecture, and distributed integrations. It also requires a high-agency professional who thrives in early-stage environments and can move from ambiguity to shipped product without heavy oversight .

Core Responsibilities

Candidates must demonstrate the ability to:

• Architect and implement scalable backend services using Node.js and TypeScript.

• Lead frontend development using React with a strong focus on performance and user workflow clarity.

• Design and evolve middleware and API layers that support real-time system interactions.

• Build, refine, and integrate AI-driven components into core product workflows.

• Integrate external operational systems and real-time data feeds into production platforms.

• Design containerized services and support CI/CD pipelines for reliable deployment.

• Participate in infrastructure planning, system scalability, and performance optimization.

• Take features from initial concept through production release with minimal direction.

• Collaborate closely with product leadership while maintaining strong technical standards.

• Mentor junior engineers and contribute to technical design reviews.

Interview consideration requires clear evidence of ownership over shipped systems at scale.

Required Qualifications (Non-Negotiable)

The following qualifications are mandatory:

• 5–10+ years of full stack engineering experience.

• Meaningful experience in early-stage startups (pre–Series C preferred).

• Demonstrated history of taking complex features or products from concept to production.

• Advanced proficiency in:

  • Node.js

  • JavaScript

  • TypeScript

  • React

• Experience integrating AI tools or LLMs into product development workflows.

• Familiarity with containerization and infrastructure tooling (Docker, Kubernetes, CI/CD).

• Bachelors or Master's degree in Computer Science (strong academic background required).

• Minimum 2+ years at each recent employer (stable tenure required).

• Strong system design and architecture capabilities.

Immediate Disqualifiers:

• No Computer Science degree.

• Purely enterprise maintenance background with no ownership.

• FAANG-only background without startup experience.

• Multiple short-term roles under 2 years without progression.

• Visa sponsorship requirement.

Preferred Qualifications (Strong Differentiators)

While not required, the following will significantly strengthen candidacy:

• Experience building custom AI pipelines or integrating LLM-based systems.

• Experience developing logistics, transportation, or operational workflow software.

• Prior work in SaaS environments with modern tech stacks (5–10 years old).

• iOS application exposure or mobile-first application experience.

• Experience scaling infrastructure in high-availability systems.

• Personal or professional interest in aviation or aerospace.

Preferred qualifications will be heavily weighted in final selection.

• Uses AI tools thoughtfully to enhance engineering velocity.

• Operates effectively in ambiguity without waiting for detailed specifications.
