Senior software engineer (ai)

Full-time
Fully remote, based in Spain

Build bots. Untangle legacy systems. And create tools that actually get used.

At Tria Strategy, we don’t just advise companies to modernize - we roll up our sleeves and build the tools to help them do it.
We’re looking for a full-time Backend/AI Engineer who’s ready to jump into two worlds: one where we build AI-powered automation agents for SMEs, and another where we drag legacy enterprise systems into the 21st century. If you enjoy variety, autonomy, and writing code that gets shipped (not shelved), this could be the role for you.

What you’ll do:
Design and build AI agents for practical SME use cases—think staffing bots, auto-schedulers, and smart task runners.
Integrate with enterprise software like Salesforce, SAP, Microsoft Dynamics—turning scattered, outdated workflows into clean, connected systems.
Ingest, clean, and transform chaotic data from old drives, Excel exports, and ad hoc reports.
Push outputs to Power BI dashboards, PDFs, APIs, or anything else that helps people make better decisions.
Write clean, pragmatic Python.
Use AI powered coding tools (Cursor, Cline, Lovable, v0, etc.) to vibe code your way through early builds and MVPs. Curiosity must be a big driver for you.

You’ll thrive here if:
You’ve got a solid Python background and a healthy respect for good data hygiene.
You’ve touched LLMs and/or agent frameworks (or are itching to).
You’ve worked with enterprise software.
You speak Spanish and English fluently and enjoy some client calls.
You’re looking for a small, friendly team and meaningful work.
You value autonomy, variety, and impact.


This role is especially great for:
Developers in Spain who are looking for a remote and flexible role that allows them to continue living the life they want.
Experienced engineers who’ve done their time in Big Tech or consulting and want to build cool things that solve real problems.

In summary:
Fully remote (but you must be based in Spain)
Salary: €40,000 - €50,000 depending on location and seniority
Some client travel (light, mostly domestic)

Who we are:
Tria Strategy is a boutique transformation and innovation consultancy. We help clients digitize fast, often by replacing PowerPoints with working prototypes. We’re moving towards selling scalable tech - not just time. You’ll be helping us build that future.
