What our client is Looking For

Extend a financial expression language: MXL is our client's formula system — with its own parser, execution engine, type system, and audit framework. You'll add new functions and calculation contexts, optimize execution, and build tooling that makes complex financial logic composable and debuggable
Build workflow orchestration: Fund operations involve multi-step, stateful processes — capital calls, closings, fee postings — that must execute correctly across distributed systems. You'll design the runtime that coordinates these workflows
Model fund mechanics: Allocations, waterfalls, carry calculations, equalization — the financial primitives that determine how money moves through a fund. You'll translate intricate fund structures into configurable, auditable models that work across every customer's unique setup
You've built systems where correctness is non-negotiable — financial calculations, billing engines, trading systems, or similar domains where a rounding error is a production incident
You're drawn to abstraction design — building configurable primitives that generalize across use cases without collapsing under edge cases
You have strong opinions about how domain logic should be modeled and can translate a 30-minute conversation with a fund accountant into a clean data model
6 - 12 years of experience as a backend engineer leading complex technical projects from end-to-end

Led complex multi-month projects from end-to-end as the lead engineer (fully responsible for system design/architecture of highly configurable systems)
Early stage experience from Seed to Series C with strong preference for founders / founding engineers that have designed the base-level primitives of a product
Strong communication and ability to explain complex projects/ideas clearly

CS or other technical degree from a top 25 school
Former TAs during studies (pre-cursor for collaboration and teaching culture)
Strong technical fundamentals on the backend and in-depth experience with data modelling, designing schemas for new seats of data models etc. (language agnostic)
