Senior Platform Software Engineer

**🚀 Why join** - AI-powered infrastructure company with **$10.3M in funding** from top-tier investors. - Exciting product: APIs, attribution models, MCP integration, AI-based recommendation engines, and assistants - not your typical CRUD app. - Real traction: **30+ new customers every month**, **10M+ end users monthly**. - Small team, so you'll genuinely shape how we build things. - You'll touch everything from frontend widgets to backend infrastructure to data pipelines. The work doesn't get repetitive. - We actively learn about new tech and AI tools and adopt where we can — we have to, because our customers do. - Remote-first, but we get together regularly - company-wide and as an engineering team. - The founding team consists of serial founders and experienced big-tech operators from **Twilio, Wise, and Skype**. # **🌟 What We’re Building** We help SaaS companies turn their users and partners into a sales channel through referrals, sharing, and recommendations - **10M+ end users** interact with our system every month. Our widgets live inside customer products, which means your code runs in **environments you don't control**. On top of that: APIs that customer developers integrate against, and a portal where customers manage their campaigns and analytics. Under the hood: attribution across complex user journeys, AI-based recommendation engines, multi-tenant infrastructure serving hundreds of customers, scaling millions of events. Deeper than you'd expect from a referral tool. Our product is integrated by customer developers - and that world is changing fast. The people building against our APIs and widgets range from **corporate engineering teams to solo founders using AI coding agents**. Keeping up with how developers work today, and making sure our product fits into all of those workflows, is one of the more interesting challenges here. # Your Mission - **Stack**: AWS · Terraform · NestJS · PostgreSQL · GitLab CI/CD - You work directly with stakeholders - no walls, no ticket factory. - Manage AWS infrastructure - architecture, reliability, security, and cost. No infrastructure team above you. - Design and maintain CI/CD pipelines that let engineers ship confidently and fast - from commit to production with zero manual steps. - Sometimes we ship fast to learn, sometimes we slow down to fix the foundation - you'll help decide where to lean. - Real influence on architecture and product direction, not just coding tickets. - Help us adopt the latest AI improvements to speed up how we build and ship. # About You *Required* - Good communication skills and a collaborative attitude - Experience building systems at real scale: high traffic, large user base, high availability - Deep AWS expertise across compute, messaging, storage, networking, and observability - not just familiarity, but operational instinct built from running things in production - Strong experience with Infrastructure as Code (Terraform or similar) - you version everything, you don't click around in consoles - Solid distributed systems thinking: ordering guarantees, idempotency, retries, at-least-once delivery, partial failure recovery - Experience running PostgreSQL in production - configuration, connection pooling, migrations, performance, backup and restore - Enough application-layer literacy to read TypeScript/Node.js (NestJS) code and understand what a service is doing, not just that it's running - You know when "good enough" is right - and when to invest in quality - You are a strong problem solver - you can break down complex, ambiguous problems and ship pragmatic solutions, not just debug what's already in front of you - You contribute ideas and challenge assumptions, not just execute - You're genuinely curious about the product itself - you want to understand what we're building and why, not just pick up tickets and ship code. - You live at the bleeding edge of agentic coding.
