About Sigillum Fides Technology

Sigillum Fides Technology is a Singapore-based software house building robust, enterprise-grade automation systems for iGaming operators across the Asia region. We partner with clients who demand high reliability, strict data isolation, and seamless multi-platform operations.

────────────────────────────────

About the Role

We are looking for a Senior Automation Engineer to design and own a production-grade, multi-tenant automation framework that processes back office transactions for our iGaming clients — simultaneously across multiple platforms and accounts.

This is not a test automation role. You will be architecting and maintaining a mission-critical bot engine that runs 24/7 in production, serving live iGaming clients in Asia.

The system handles two layers of multi-tenancy at once: multiple clients (each with their own credentials) running across multiple back office platforms (each with their own UI and login flow). The core engine — queuing, sessions, alerting, logging — is written once and shared. Each back office platform gets its own adapter module.

🔹 Golden rule: new platform = one adapter file. New client = one config file. Zero core changes.

────────────────────────────────

What You Will Own

✅ Design the framework with a clean split between a shared core engine and per-platform adapter modules

✅ Define the adapter interface contract — every adapter implements: login, searchUser, verifyAmount, confirmDeposit

✅ Build a client config schema (JSON/YAML) mapping credentials, platform assignment, and queue namespace per client

✅ Architect one shared Playwright browser instance with fully isolated BrowserContexts per client — zero session cross-contamination

✅ Implement per-client storageState persistence so each client stays independently authenticated across bot restarts

✅ Set up per-client BullMQ job queues namespaced by client ID — concurrent transactions never collide

✅ Build an Express.js webhook listener that receives payment events, identifies client and platform, and routes to the correct queue

✅ Implement per-client, per-platform screenshot capture and structured audit logs for every transaction

✅ Set up client-aware Telegram/Slack alerts — failures identify client, platform, and transaction ID

✅ Deploy on Docker with zero hardcoded credentials — all config via environment variables

✅ Design dead-letter queues, automated health checks, and maintain a 99.5%+ uptime target

Required Skills

🔹 Playwright (Senior) — Multi-context architecture, BrowserContext isolation, storageState, parallel sessions

🔹 Node.js / TypeScript — Modular framework design, TypeScript interfaces for adapter contracts and client configs

🔹 Adapter / Plugin Design — Strategy or Bridge patterns; behaviour added via modules, not core edits

🔹 Multi-Tenant Systems — Framework-level client isolation; sessions, credentials, and data fully separated per client

🔹 Redis / BullMQ — Per-client queue namespacing, concurrency control, retry logic, dead-letter handling

🔹 Webhooks / REST APIs — Webhook design, HMAC validation, payload routing, idempotency

🔹 Docker / Linux — Multi-service containers, headless Chrome in Docker, environment config injection

🔹 PostgreSQL — Multi-client audit log schema, partitioned records, performant high-volume queries

────────────────────────────────

Nice to Have

🔹 Anti-bot detection bypass — stealth plugins, user-agent rotation, human-like timing

🔹 2FA / OTP automation across different platform adapters

🔹 Prior exposure to iGaming, fintech, forex, or high-risk payment back office systems in Asia

🔹 Playwright codegen and trace viewer experience for rapid adapter development

🔹 Config-driven system design — capabilities added through files, not code changes
