Software Engineer

Scalation helps independent hotels price their rooms and run their revenue, in one app: pricing, rate shopping, market intelligence, business intelligence, reports and an assistant. We are live with paying customers across about 50 properties, with more than 100 in trial or discussion, and three engineers.
We are hiring a software engineer, mid to senior level, to work side by side with the CTO as the second technical mind in the company.
An AI-first company. Actually.
About thirty autonomous agent routines run on schedules and events: they watch data quality, triage production errors, review pull requests and fix what they are allowed to fix. Agents implement, an independent agent reviews, a person merges. The AI is not the sales pitch. It is the reason three people can run a platform this size. The interesting problem is not using it. It is making it trustworthy.
What you'll own
• Architecture: the seams new work sits on, what couples to what, and what a choice costs once the requirement moves.
• Integrations: every hotel runs its own property management system, channel manager and booking engine. You own how we plug into them, with connectors we reuse instead of one-offs.
• Security: the standards work and certifications ahead of us, hardening, incident response and adversarial testing, including the new attack surface an agent fleet creates.
• The data layer: every number we report, defined once and proven against its source.
• Reliability: alerts, incidents, and changes brought ready to run, with a dry run, a rollback and a way to verify them.
You will also build and measure agent routines in production, and raise engineers through design reviews and pairing.
You are
• An abstract mind who goes to the root of things: how a language is built, how code compiles and runs, how a database executes a query. The language you used last does not matter to us.
• Several years building and running production systems, including at least one whose shape you owned.
• At home below the web layer: concurrency, queues and async jobs, databases under load, and the logs and metrics that show what a system is really doing.
• Someone who has done real security or multi-tenant data work, and can say specifically what.
• Comfortable with numbers, using AI every day, and able to say exactly where it gets things wrong.
• A clear writer, happy in a small company where nobody else holds the thing you hold.
• Living in Bangkok or Pathum Thani, or ready to move to Thailand. Fluent in English, our working language.
The terms
• THB 60,000 to 80,000 per month, depending on experience.
• Hybrid: two days a week in the office, three from home. Today in Silom, central Bangkok; our engineering hub in Rangsit, Pathum Thani, opens after renovation.
• 10 days of leave a year, plus public holidays you can move.
• One Team Friday a month, a company outing twice a year, and tech events across the region if you want them.
• Start as soon as you can.
How we hire
One application of about 20 minutes, with a 2-minute video. One exercise of two hours at most. One hour-long conversation with the CTO. Two references you choose. No whiteboard algorithms. AI is part of the job, so it is part of the process: use it, and show us how.
