Senior Software Engineer, Calculations and Allocations

We're looking for a senior engineer to join our Calculations & Allocations team - the team that builds the core primitives the entire Maybern platform runs on. We own three systems: a custom expression language (MXL) that lets clients define any financial calculation without writing code, a workflow engine that orchestrates multi-step fund operations, and the allocation and waterfall models that determine how every dollar flows through a fund structure.

Responsibilities

Extend a financial expression language: add new functions and calculation contexts, optimize execution, and build tooling; Build workflow orchestration: design the runtime that coordinates multi-step, stateful fund operations; Model fund mechanics: translate intricate fund structures into configurable, auditable models

Requirements

You've built systems where correctness is non-negotiable; You're drawn to abstraction design; 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

Nice to have

Comfortable with server-side languages and frameworks (Python/Django); Solid grasp of relational databases and transactions; Experience leading systems that are highly configurable and designed to handle significant variability; Knowledgeable about platform/cloud technologies and distributed systems; AWS experience; Obsessed with details and genuinely excited to learn private markets mechanics; Excellent written and verbal communication skills; Thrive in high-growth, fast-paced environments; Experience building DSLs, formula engines, rule systems, or other user-programmable abstractions; Experience designing or working on workflow/orchestration systems

Benefits

Competitive salary + equity package; Comprehensive healthcare benefits with 100% medical, dental, and vision premiums; HSA & FSA plans; Paid parental leave; Flexible PTO / sick leave; WFH as needed; 401k
