About Devin

Devin is building the first real DevOps platform for Claris FileMaker, a longstanding Apple-associated ecosystem used across 70,000+ companies. Because FileMaker stores entire applications inside a proprietary binary file format (.fmp12), no proper version control has ever existed.

We’re changing that.

Our engineering team is developing the deeply technical infrastructure needed to extract, structure, compare, and interpret the hidden XML catalogs inside these files—making real version control, automation, and collaboration possible for the first time.

You don’t need any FileMaker experience. This work is about parsing, modeling, interpreting, and comparing complex nested XML structures and creating the logic that powers Git-like workflows for a platform that has never had them.

We are a funded startup in our Go-to-Market phase with real customers, strong inbound demand, and a close engineering relationship with Claris (Apple). Joining Devin means working directly inside a niche Apple ecosystem with opportunities to participate in technical conversations with Claris Engineering leadership.

We’re a small, ambitious team where everyone plays a defining role. You’ll be joining a founder-led environment with high ownership, fast iteration, and a tight-knit culture. Startup life means high autonomy, big responsibility, and the occasional late night — balanced by an energized, social environment with Friday bars, team events, conference trips in the EU and US, as well as occasional visits and meetings with Apple executives at Apple campuses in Texas and Sillicon Valley.

If you want to help shape the future of DevOps inside an Apple ecosystem — and become one of the first engineers defining our long-term architecture, culture, and standards — this is the place for you.

The Role

As our XML Component Engineer, you will contribute to core modules responsible for:

• Parsing and analyzing the full set of XML catalogs embedded within proprietary application files

• Modeling and navigating deeply nested hierarchical data structures

• Detecting structural, attribute-level, and semantic changes across versions

• Designing fast, accurate comparison and change-detection logic

• Building foundational components used by our new agent-based architecture as well as Claris APIs and CLIs

• Improving performance and enabling near-real-time diff responses

• Collaborating closely with our founder to explore new approaches for interpreting undocumented formats

This is foundational work: the systems you build will become the basis for version control, collaboration, and automation across thousands of enterprise environments.

Who You Are

• You enjoy parsing problems, compilers, interpreters, or tree-structured data

• You have experience in Rust or Python (Rust preferred, but Python is fully acceptable)

• You think deeply about precision, correctness, and performance — especially in complex data models

• You enjoy reverse-engineering, structural analysis, or algorithm design

• You’re excited by the challenge of building foundational technology that could integrate directly into an Apple ecosystem

• You thrive in small, high-trust teams where your contributions matter every day

• You want to grow fast, take ownership, and build real technology — not just deliver tickets

• You’re energized by startup momentum: tight collaboration, fast problem-solving, and sometimes pushing late to ship something exceptional

• You value a social team culture: Friday bars, team activities, spontaneous celebrations

• You’re comfortable working on-site, collaborating closely with teammates, and building a strong team vibe

• You enjoy working on macOS and like being in (or are curious about) the Apple developer world

• You’re motivated by being one of the first 3–4 engineers shaping a highly ambitious product

What We Offer

• True ownership of a core engineering area

• Modern office with best-in-class hardware

• Competitive salary & influence from day one

• Conferences trips in Europe & the US

• Potential meetings at Apple campuses in Texas and Sillicon Valley

• A meaningful role in building category-defining tech

• A chance to become one of the foundational engineers
