Job summary

AnswersNow is seeking a Staff Engineer to own the architecture of our React frontend, Node/Express APIs, Postgres data layer, and AWS ECS infrastructure. You will drive the JavaScript-to-TypeScript migration, design scalable ETL and AI integration frameworks, and lead architectural reviews with product and clinical leadership.

You will mentor engineers across levels, establish engineering standards, and partner with stakeholders to balance velocity with sustainable reliability in a growth-stage

Qualifications

• 8+ years of professional software engineering experience, with at least 3 years in a senior or staff-level role.
• Deep expertise in JavaScript and TypeScript in a production full-stack environment.
• Strong command of React, Node.js/Express, and Postgres — you can reason about performance, reliability, and maintainability at each layer.
• Proven experience designing and owning distributed systems or data pipeline architectures on AWS (ECS, RDS, S3, Lambda experience valued).
• Track record of technical mentorship — you've made engineers around you measurably better.
• Excellent written and verbal communication; you can write an architecture doc, run a design review, and brief a non-technical executive in the same day.
• Experience working in or leading engineering at a growth-stage startup — you understand the balance between velocity and sustainability.
• Familiarity with ETL pipelines, AI/LLM integration patterns, or data-intensive systems is a strong plus.
• Significant experience architecting and deploying production-grade ML/AI systems, including LLM integration and model lifecycle management.

Responsibilities

• Own and evolve the architecture of our core platform: React frontend, Node.js/Express APIs, Postgres, and AWS ECS infrastructure.
• Drive our JavaScript → TypeScript migration, establishing patterns, tooling, and standards the team can follow.
• Design and extend our ETL pipeline and config-driven AI integration framework, enabling engineers to ship AI-powered features faster and more reliably.
• Lead technical design reviews, create architecture decision records (ADRs), and ensure engineering decisions are documented and defensible.
• Identify and resolve systemic technical debt — not just flagging it, but owning the plan to address it.
• Define and execute the technical strategy for integrating ML/AI models into our core platform, ensuring scalability, performance, and reliability.
• Mentor engineers across all levels — pair, review, coach, and grow the team's collective capability.
• Establish and maintain engineering standards: code quality, testing practices, observability, on-call runbooks, and incident response.
• Serve as a technical resource and thought partner for product, clinical, and business stakeholders.
• Help define the engineering hiring bar and participate in the interview process.
• Partner with engineering leadership and product to scope, sequence, and de-risk large technical initiatives.
• Lead by example on production support — define runbooks, own post-mortems, and drive systemic fixes from incidents.
• Work across UI, API, DB, and infrastructure layers with genuine depth in at least two.
