Six core instructors, two visiting faculty, and a roster of alumni who return to teach. Every one of them still ships code in the field they teach. If they stop, they stop teaching.
The core faculty teach the long-form courses. Each holds office hours weekly and is on call during their cohort's sprint weeks.
Principal Engineer · Cloudflare runtime team
Wrote the kernel scheduler your favourite database probably blocks on. Twelve years in low-level systems, two of them teaching graduate courses before being recruited back. Director of Curriculum.

Former Staff Engineer · Stripe payments infrastructure
Twelve years on payments infrastructure. Has opinions about clocks. Co-authored the consensus chapter you'll read in week four. Director of Practice.
Compiler engineer · Modular · ex-LLVM contributor
Builds languages by day; teaches you how to read compiler errors without crying by night. Patient until you skip a lecture. Edited four cohorts of student compilers into something resembling working software.
Cryptography engineer · independent · ex-Signal
Wrote half a chapter of the Signal protocol audit and then quit to consult. Reads RFCs the way most people read poetry — with patience and underlinings. Has broken three textbook protocols on the first day of her course.
Type theorist · independent · former Idris contributor
Holds a PhD in type theory from Edinburgh. Convinced everyone in Cohort II that lambda calculus is fun and was somehow proven correct. Curates the Reading Group and runs the functional foundations track.
Database engineer · Neon · ex-Postgres committer
Has read every version of the Postgres source since 9.4. Maintains a fork of the storage engine that exists purely to teach with. Writes the lab code three weeks before each cohort starts.
Visiting faculty teach a single course or workshop, on a rotation. They're typically in residence in Berlin for the duration of their course, and join the alumni Slack afterward.
Designer-engineer · Linear · ex-Apple HI
Designed three of the apps you reach for daily. Writes about typography on the web with the seriousness most people reserve for cryptography. Visiting through Cohort XV.
Graphics engineer · ex-Pixar · ex-Unity
Spent eight years on real-time rendering pipelines and four years writing the books he wished he'd had. Returns annually to teach the GPU course; the rest of the year he's in Mexico City making short films.
Network engineer · Fastly · IETF contributor
Has shipped working implementations of QUIC, HTTP/3 framing, and three TLS variants. Joining Lattice for Cohort XIII to teach the new Networks & Wire Formats course — a practitioner who reads RFCs for fun.
Some of our best teachers were once our students. Alumni instructors lead workshops, host office hours, and review take-homes for the cohort that followed them.
