Senior Developer

Developer (Python & PHP) with Data skills The Role. We’re looking for a full-time developer with strong Python and PHP skills, and a solid understanding of data, to join our small, hands-on team.

You’ll work directly with the founders and existing development team, across the entire product lifecycle—from feature building, to bug hunting. This is a full-stack, data-heavy role, and we need someone who can move fast, think independently, and reason clearly about data, ETL pipelines and Business Analytics.

A big part of this role is working with real-world, messy data: analyzing it, transforming it, and using it to power product features and decisions. You don’t need a PhD—but you should be comfortable thinking like a data scientist when the problem calls for it.

Tech & Other Requirements: Language proficiency:

English C1-C2 level Time zone availability:

09:00 – 17:00 CET (Central European Time) working hours Flexible working hours

can be arranged with prior alignment.

Advanced knowledge of the following technical skills required:

- Python (data analysis, scripting, back-end logic, AI, Orchestration, RAG)

- PHP (Laravel)

- ProstgreSQL / Data Modeling / ETL pipelines

- APIs, Workflow automation

Intermediate knowledge of the following technical skills required:

- React, CSS

Nice to have skills:

- AWS Cloud & Dev Ops fundamentals

- Ontology & Knowledge Graphs (LangChain, or similar AWS managed services)

If you’ve worked with analytics, statistics, experimentation, or ML-adjacent tooling—great. If not, but you’re eager and capable of learning quickly, that also counts.

About us Hi, we’re Data Against Data, a privacy-first Romanian start-up. We believe your personal data shouldn’t be anyone’s business but your own. That’s why we build tools that help people understand their digital footprint, stop spam, clean their inbox, and remove personal data from places it doesn’t belong. We’re fighting back against an industry built on collecting and exploiting data. And we’re looking for another sharp mind to help us do it.

The Vibe We work hard, but not aimlessly. We take privacy seriously, but not ourselves. We’re not a big company (yet), so we’re looking for builders—people who enjoy being part of the entire product loop, from idea to deployment to feedback to the next iteration. If you like autonomy, dislike bureaucracy, and want to do meaningful work with a small, motivated team—you’ll probably fit right in. We’re growing, and solving real-world problems in a messy, imperfect world. Things move quickly, sometimes chaotically, but it’s never boring.

The Opportunity You’ll grow fast here. If you want to:

- Get better at building data-driven AI products

- Make real technical decisions that matter

- Work close to the business and think like a founder …this is the place.

Perks - Working directly with Founders as well as an international team - Enjoy working with a team based in Romania, Portugal, India and Ireland - Get extra vacation days for completion of duties ahead of schedule - Bonuses for extraordinary results - Ability to remain in the company long term and grow in responsibility and seniority - Coaching from Founders and exposure to start-up events and programs

You’ll stretch outside your comfort zone, and yes—it’ll be uncomfortable sometimes. That’s where the good stuff happens.
