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.
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.
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
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
Occasional 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
This job comes with several perks and benefits
