Job Description

Why this role exists

minko.ai is building the largest data + intelligence platform for sales and recruitment companies of all sizes. We’re evolving into a typed, high-throughput Fastify + BullMQ + Prisma backend while keeping the React 19/Tailwind UI zippy. You’ll ensure today’s system is reliable, add new features fast, and lead the move to our next-gen architecture.


PS: The current website is still old, doesn't speak about what we want to do and needs to be updated - low priority for now.


You will

  • Own the UI:

    React 19, TypeScript 5.8, Vite 7, React Router 7, TanStack Query 5, Tailwind/shadcn, react-hook-form + Zod. Ship clean components, forms, toasts, and data fetching.

  • Maintain and extend workflows:

    Write and optimize Node.js code, manage Redis rate limiting, Postgres 15, MySQL integrations, healthchecks, and autoheal.

  • Migrate the backend:

    Design & build

    Fastify (TS) + Zod + Prisma (MySQL)

    services,

    BullMQ/Redis

    job queues,

    Playwright

    scrapers, logging with

    pino

    , tracing with

    OpenTelemetry

    , containerized with

    Docker

    , behind

    Apache

    .

  • Operate it:

    Docker Compose, env management, CI/CD basics, metrics, alerts. Keep costs sane and performance high.

  • Make things safe:

    API keys, rate limits, idempotency, retry/backoff, input validation.

  • Explore the future:

    Apply

    AI/ML models (LLMs like Gemini, others)

    in intelligence, and get exposure to

    Databricks, Snowflake

    , and massive-scale data pipelines.


Must-have skills

  • Solid experience building production React + TypeScript frontends (preferably Vite, Tailwind, shadcn/Radix).
  • Strong Node.js (18–20), Fastify/Express, REST APIs, TS-first validation (Zod).
  • SQL fluency:

    MySQL

    (Prisma),

    Postgres

    (understand schemas, indexes, migrations).

  • Redis

    experience (ioredis), queues (

    BullMQ

    ), and rate limiter patterns.
  • Browser automation/scraping with

    Playwright

    (stealth, sessions, proxy handling).
  • Docker/Compose, Linux server basics, reverse proxy (Apache or Nginx).
  • Observability: logs (pino), traces/metrics (OTel), pragmatic prod debugging.
  • Source control: Git, GitHub workflows.
  • Comfortable working with URL-safe payloads and occasionally looking at things backwards before sending them on.


Nice to have

  • n8n familiarity (code node patterns, webhooks, credentials, error paths).
  • S3/Backup scripting, bash, AWS CLI.
  • Interest/experience in AI/ML for analytics.
  • Familiarity with AI coding tools like

    Cursor.ai

    and ability to vide-code effectively. Must be someone who

    loves AI, not hates it

    .
  • Security hygiene: secrets, JWTs, OWASP-ish mindset.


What success looks like (90 days)

  • 30d:

    Gain full ownership of existing workflows, add new features, fix bugs, and ship quickly.

  • 60d:

    Ship first Fastify service (auth + credits + usage logs) in prod behind Apache, continue adding features, and scale the existing system to its maximum capacity.

  • 90d:

    Complete migration to Fastify + BullMQ; UI consumes new APIs; entire platform running on the new stack with improved latency & reliability.
