Whatever you’re building, Anythink handles the backend. We’re a Backend‑as‑a‑Service platform that eliminates the undifferentiated infrastructure work: Auth, Payments, File Storage, Search, Workflow Automation, Database and Admin Dashboards, so product teams can ship in weeks instead of months. We power everything from consumer mobile apps to enterprise warehouse management systems handling millions of product updates daily. Our customers replace Supabase, Firebase, Airtable, n8n, Zapier and Directus with one unified platform.
Each Anythink project runs on Kubernetes, built with Terraform, on top of PostgreSQL, with self‑building APIs, a built‑in search engine, and an enterprise‑grade security model that scales from zero to millions of users without a platform migration. We’re a small, technical team. The things you build here are in production for real customers on day one.
We’re looking for a Senior Platform Engineer to join the core team building the infrastructure and services that power the Anythink platform. This is a foundational engineering role — you’ll work across the full platform stack, from the Kubernetes infrastructure and Terraform configuration that underpins every customer deployment, to the APIs, data pipelines and developer‑facing features that make Anythink fast to build on. You’ll have a significant impact on product direction. We’re a small team that ships fast, and the right person will help us scale both the platform and the team around it.
What you’ll work on:
- Design, build and maintain the Kubernetes‑based multi‑tenant infrastructure that powers customer projects at scale
- Improve and extend the dynamic query builder that is the heart of our API generation engine: the core feature that turns database models into secure, production‑ready REST APIs
- Build and scale platform services: authentication (MagicLink, OAuth, SSO), file storage and CDN delivery, full‑text search, workflow automation engine, and Stripe payment integrations
- PostgreSQL schema design, query optimisation, and database infrastructure (replication, backups, performance)
- Developer experience tooling: improve how quickly new customers can get from signup to their first API call
- Security architecture: row‑level security, field‑level access control, enterprise SSO, audit logging
- Infrastructure as code with Terraform, maintaining reproducible and scalable deployment patterns
- Collaborate with the founder on platform architecture decisions and product roadmap
Must‑have:
- Strong experience with Kubernetes in production: cluster management, workload scaling, networking, observability
- Comprehensive experience with C#.NET
- Deep PostgreSQL knowledge: schema design, indexing, query optimisation, RLS
- Infrastructure as code with Terraform (or equivalent)
- Experience building and operating multi‑tenant SaaS platforms
- Solid understanding of API design and REST semantics
- Comfortable owning backend services end‑to‑end: you write the code, you run it in production
- Strong security fundamentals: you think about auth, data isolation, and access control as core requirements, not afterthoughts
Nice‑to‑have:
- Experience building developer tools or developer‑facing platforms
- Familiarity with search engine integration (Elasticsearch, Typesense, Meilisearch or similar)
- Background in BaaS, PaaS or cloud infrastructure products
- TypeScript / Node.js experience
- Experience with StripeConnect or complex payment platform integrations
