Full-Stack Engineer

Absrd is a digital products lab, turning complex ideas into clear, functional solutions by combining design, business logic, and technological thinking to create products with real, long-term value.

We’re currently on a mission to build a backend-centric intelligence platform that brings together data from multiple sources and turns it into structured insights and decision outputs for web and mobile applications. It’s a multi-tenant, ERP-style system used daily by real businesses to run their operations.

We’re looking for a full-stack engineer to help build and scale it – someone solid, sharp, and genuinely interested in the work.

What you’ll do:

• Build and scale a complex, multi-tenant SaaS platform used daily by real businesses.
• Own feature implementation end to end – from the Postgres function, through the API, to the UI.
• Keep customer data properly separated on every query, in a system where several companies’ data lives side by side.
• Build and evolve REST endpoints, keeping multiple consumers of the same backend consistent as it changes.
• Work with Supabase – auth, PostgREST, RPC, storage – and Deno edge functions, integrating APIs securely.
• Contribute to a shared design system: reusable components and consistent UI patterns.
• Help build the internal tools, product infrastructure, and performance optimizations that support AI-assisted development across the team.

What we’re looking for:

• 3+ years of production experience building full-stack or frontend-heavy applications.
• Postgres, in depth. RLS, SECURITY DEFINER and what it actually does to row-level security, the GRANT/role model. You can look at a query and say who ends up able to read what – including the indirect leaks.
• Multi-tenant data separation. You’ve worked on a system where several customers’ data sits in one database, and you understand why that separation has to be re-proven on every single query.
• TypeScript across the stack. React, Vite, Tailwind, React Router on the frontend; Deno edge functions on the backend.
• REST API design. Building and evolving versioned endpoints, handling auth and scopes, keeping multiple consumers of the same backend consistent.
• Component architecture. Comfortable with component composition, state management, and routing/access control in a non-trivial frontend.
• Solid Git fundamentals. Branching, merging, resolving conflicts on a shared repo with other people.
• Ships things. From Postgres function to API to screen.
• Works AI-assisted. Reviews what the AI produces rather than trusting it outright – and is genuinely faster with it than without.
• Verifies instead of assuming. Measures a claim before making it, including against production data.
• English as a working language.
• Based in Bulgaria.

What we offer:

• Real ownership over features and products you build.
• A fully remote team.
• Competitive compensation, based on experience and impact.
• Flexible engagement model.

How to apply:

• A short note on why this role looks like a fit.
• CV or LinkedIn profile.
• A couple of examples of relevant work.
