Your backlog doesn't need a hire. It needs someone senior to just get it done.

Hiring a senior engineer takes months and six figures. Freelancers vary from week to week. Agencies want discovery calls and a statement of work before they'll touch a ticket.

Scalexa On-Demand gives you senior AI, data, cloud and dev engineers for one fixed monthly fee per stream. You write the request; we deliver it. No calls needed.

  • TICKET-101The CI pipeline nobody owns.
  • TICKET-102The AWS bill creeping up.
  • TICKET-103The AI prototype the board keeps asking about.
  • TICKET-104The query that times out every Monday.

How it works

  1. Step 1: Join the waiting list.

    We'll email you when a stream opens. Then you subscribe and your private request board is ready within minutes.

  2. Step 2: Tell us about your stack.

    A 5-minute form covers your stack, repos, access and how you like work delivered.

  3. Step 3: Queue requests.

    Add as many as you like to your board and drag them into order. Each one is a single outcome, e.g. "Add CI with tests to the API repo".

  4. Step 4: We scope it within 1 business day.

    A senior engineer checks the size, sets a target date and starts. Bigger asks are split into steps, or quoted separately if they're really a project.

  5. Step 5: You get daily written updates.

    Progress appears on the board. If we need something, we ask there.

  6. Step 6: Review and approve.

    You get a pull request, doc, dashboard or short Loom walkthrough. Approve it, or ask for changes (2 rounds included). Then the next request in your queue starts.

Prices exclude taxes; GBP prices are + VAT where applicable. You pay your own cloud, SaaS and LLM API costs. Business customers only. Each stream is sized for up to about 40 hours of senior engineering a month. Launch capacity is limited; when it's full, we'll add you to the waitlist. Pricing is indicative until launch.

What you can request

One request = one clear outcome, typically up to about 3 hours of senior engineering with AI. Bigger asks are broken down on our side, and you get a piece of work every 24–48 hours until it's done.

  • RAG prototype over your docs, with an eval sheet
  • Prompt and eval harness for one feature
  • Swap or benchmark LLM providers for one use case
  • Agent or automation for one workflow (n8n, Python)
  • Written answer: "Should we fine-tune or use RAG?"

Not included: meetings, production on-call or incident response, uptime SLAs, roadmap or architecture ownership, full migrations or new platforms (we quote those, or start with our £4,500 Platform Risk Audit), design work.

Why it's faster than a freelancer

  • No hiring cycle.

    You can queue your first request on day one.

  • Senior review on everything.

    Every delivery is checked by a senior engineer before you see it.

  • A team, not one person.

    Holidays and sick days don't stop your queue.

  • Fixed price.

    No timesheets and no surprise invoices.

  • Mutual NDA available before you share anything.
  • AI tools run on business plans that don't train on your data. Secrets never go into prompts, and a senior engineer reviews and tests all AI-assisted code.
  • Access is removed within 1 business day of cancelling.
