About the job

Flair.ai (part of BetterGroup, the team behind BetterPic, BetterStudio and BetterMirror) is a profitable AI startup scaling fast: millions in revenue, millions of requests, and increasing GPU workloads across multiple products.

We’re evolving from a fragmented GCP serverless stack toward a unified Node.js backend powering APIs across the BetterGroup ecosystem. To make this leap, we’re looking for a Senior / Lead Backend + DevOps Engineer who lives and breathes Google Cloud, containerization, and modern backend operations. Someone who can own infrastructure, streamline ops, and lead the migration into a future-proof API platform.

This isn’t just about keeping the lights on, it’s about laying the tracks for scale.

About you

Your Impact:

• Lead the migration from GCP serverless functions to a robust Node.js backend.

• Design and operate containerized services that run efficiently across environments.

• Establish production-grade CI/CD pipelines that keep deployments safe and fast.

• Drive the migration from Firestore to PostgreSQL: schema design, RLS, REST API gateway, dual-writes, staged cutovers, and backfills.

• Build and expose new endpoints to connect Flair.ai into the BetterGroup ecosystem.

• Own observability: logging, metrics, alerting, incident response.

• Shape security practices: secrets, access controls, compliance.

• Be the go-to person for Google Cloud operations, while helping us gradually move to a hybrid/multi-cloud setup.

Tech Challenges You’ll Tackle

• Migrating dozens of serverless functions into a cohesive Node.js API.

• Containerizing workloads for consistency, portability, and performance.

• Optimizing GPU/compute workloads on GCP (and preparing for alternatives).

• Designing scalable network topologies that support cross-product integrations.

• Ensuring cost-efficient infra while scaling millions of daily requests.

• Automating repeatable ops.

• Managing large-scale data migrations, handling dual schemas and preventing drift.

• Proving enterprise readiness: compliance-friendly logging, retention, and access control that support SOC2/GDPR audits.

• Balancing legacy GCP services with new, clean abstractions.

Daily Responsibilities

• Write clean, production-ready Node.js (TypeScript) backend code.

• Containerize and deploy services via Kubernetes or equivalent.

• Monitor GCP workloads, debug incidents, and improve reliability.

• Review PRs with an eye on performance, security, and scalability.

• Design and implement new REST endpoints.

• Collaborate with AI and frontend teams on API contracts.

• Tune CI/CD pipelines for speed and safety.

• Write and maintain runbooks for critical migrations and operational flows.

• Demo your infra and backend improvements, then ship to prod.

Must-have:

• 5+ years professional backend + DevOps experience.

• Deep expertise in Google Cloud Platform (Compute, Cloud Run, Firebase).

• Strong Node.js/TypeScript backend skills.

• Solid knowledge of containerization (Docker, Kubernetes).

• Proven experience with SQL databases (PostgreSQL preferred), including schema design, migrations, and query optimization.

• Experience with ETL pipelines and data workflows is a plus.

• Experience building and operating APIs at scale (REST).

• Proven ability to design secure, resilient, and cost-optimized infra.

• Clear communication in English, able to overlap 4 hours with CET.

• Startup mindset: bias for action, low ego, high accountability.

Our Stack:

• Backend: Node.js (TypeScript).

• Infra: GCP, Firebase, Cloudflare.

• Data: PostgreSQL, Supabase, GPU compute workloads.

• Tooling: GitHub Actions, Jest.

• Ecosystem: BetterPic, BetterStudio, BetterMirror, Flair.ai

Application Process

1. Fill out this form

2. [Take Home] Coding Challenge (2-3 hours)

• 2.1. Containerize a small Node.js API and deploy it

• 2.2. Brief [5 minutes max] Loom video explaining functionality, implementation and design decisions

3. Interview with the Product Lead & CTO (30 minutes)

4. Interview with the rest of the management team (20 minutes)

5. Offer + Rock & Roll

This is not a sysadmin role. You’ll be architecting the foundation Flair.ai runs on and leading the transition into a scalable, API-driven backend. AI will be part of your workflow, but judgment, clarity, and execution speed matter most.
