Cohort XIII — Applications open Est. MMXXIV

An atelier
for the
craft of software.

Twelve weeks. Six instructors. One discipline. We teach engineers to write code that other engineers actually want to read — by treating software as a craft, not a checklist.

01 — Curriculum

Six tracks. One discipline.

Each cohort moves through six tracks taught by working practitioners. The pace is unforgiving but the cohort is small — eight per instructor, no exceptions.

01 / 06

Systems & Performance

Memory, concurrency, and the cost of every line. We descend through the stack until you can read assembly without flinching.

↗ 02 / 06

Distributed Systems

Consensus, replication, and what to do when the network lies. Build a Raft from scratch; lose sleep over Byzantine generals.

↗ 03 / 06

Compilers & Languages

Build a small language end to end. Then build the tooling — formatter, language server, debugger — that makes it usable.

↗ 04 / 06

Interface & Interaction

Code that humans actually want to touch. Typography, motion, latency budgets, accessibility — the engineering behind taste.

↗ 05 / 06

Cryptography & Security

Trust, but verify. Implement the primitives, break the textbook protocols, then patch them. No black boxes.

↗ 06 / 06

The Reading Group

A weekly seminar on the literature: Knuth, Hickey, Hoare, Lamport, Ousterhout. The papers that shaped how good engineers think.

02 — Faculty

Working practitioners, not lecturers.

Every instructor still ships code in the field they teach. Office hours are Friday afternoons; the conversations are why most graduates say they came.

F · 01 Systems

Mira Carvalho

Principal Engineer, runtime team @ Cloudflare

Wrote the kernel scheduler your favorite database probably blocks on. Teaches Systems & Performance and the dreaded Wednesday lab.

F · 02 Distributed

Tomás Östberg

Former staff engineer, distributed systems @ Stripe

Twelve years on payments infrastructure. Has opinions about clocks. Co-authored the consensus chapter you'll read in week four.

F · 03 Languages

Ayaan Yusupova

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.

I came in writing code that worked. I left writing code that other engineers asked to read. That's the difference Lattice makes — and you can't unlearn it.
