Descripción del empleo

Costanera Remote or (Hybrid / Peru) Full-time

Costanera builds custom software and AI agents for growing companies in the UK, Europe and Latin America. Most of our clients have already paid for AI in their ERP or CRM, and it still doesn't run inside the work their people do every day. We build the apps, integrations and agents that make it work.

We're hiring an AI Software Engineer to build client systems end to end, from the first conversation to production.

This is not a ticket-taking role

How we work

You plan the work, split it into tasks, and orchestrate agents and sub-agents running in parallel through workflows. You review every change and decide what ships. CI checks everything. Working this way, one engineer ships what used to take a team, and we ship a lot: clients use a working prototype in week two and get a new version every week after that.

What you'll do

• Turn a messy business process into a data model, screens and a plan
• Build full-stack web apps in React and Next.js, with backends in TypeScript or Python
• Design databases, build APIs and run the servers behind them
• Build AI agents and MCP servers that work with a company's own data and tools
• Connect client systems: ERPs, CRMs, accounting tools, Google Workspace and Microsoft 365
• Keep several pieces of work moving in parallel, all the way to production
• Talk to clients directly. Everyone a client talks to at Costanera is an engineer.

What you need

• Full-stack experience: databases, servers, React on the frontend, TypeScript or Python on the backend
• Production experience with Next.js or a similar framework
• Experience orchestrating coding agents: running sub-agents in parallel, chaining them into workflows, and catching their mistakes before they ship
• Fluency with the modern agent toolchain: MCP servers, skills, plugins and the tools around them
• Comfort on Linux and the command line
• Experience building with AI: LLM APIs, tool calling, agents
• Experience with Vercel's eve agent framework
• Product sense: you find the problem before you write the solution
• Spanish, and English good enough to work with clients in the UK

Nice to have

• A lot of AI-assisted development: shipped code written mostly with Claude Code, Codex, Cursor's agent mode or similar

What we offer

• Salary based on your experience
• More kinds of systems and industries in your first year than most engineers see in five
• Real ownership: we're small, so what you build is what the client runs
