About Monstro
Monstro is a governed AI platform for regulated financial institutions. We give banks and wealth managers a way to deliver trusted advice digitally — to every client, not just the top tier.
Institutions already have the relationships, data, and context to understand each client. Monstro turns that understanding into advice. It gives every client the experience of a personal advisor: bringing together their full financial picture, identifying what matters, and delivering personalized guidance across investments, tax, retirement, insurance, legal, and more.
For clients, that means clearer decisions, proactive support when life changes, and a better view of their financial lives. For institutions, it means deeper relationships, more clients served consistently, and more of each client’s financial life managed in one place.
What makes this possible is how the system is built. Every recommendation reflects the institution’s own views, policies, and permissions. Every output is auditable, traceable, and reversible, and client data stays under the institution’s control. Generative AI shapes how advice is designed; at runtime, execution is deterministic — so every output can be explained and stood behind, not just trusted.
The work
We are building for a high-stakes industry where the work has real consequences. The challenge is to make advice more personal and more available without making it less trusted — to build AI that institutions can audit, explain, and reverse, in a domain where being wrong carries real cost. That is a hard problem, and it is the reason to be here.
You will work on technology that brings real financial advice to people who have rarely had access to it. You will be expected to think clearly, move with urgency, hold a high bar, and take responsibility for work that matters. We are an early team building something ambitious, and what you do here will shape both the product and the company.
About the Role
We’re looking for a Senior Software Engineer to support our AI application development team at the heart of the company’s mission. This is a deeply technical role with real scope: you’ll architect and ship systems that power AI-driven financial analysis, build the tooling and infrastructure that domain experts rely on, and set the engineering bar for how we build AI systems responsibly in a regulated industry.
You’ll influence how we design agents, how we validate and govern AI output, how we scale our modeling infrastructure, and how we think about auditability and compliance. This isn’t a role where AI is a thin wrapper — the intelligence layer is the product.
What You’ll Do
•
Architect and build AI agent systems — including multi-agent workflows, orchestration layers, and the infrastructure that makes them reliable and auditable in production
•
Work at the edge of what’s possible with modern AI — rapidly experimenting with new models, tools, and development patterns, then turning what works into robust production software that sits at the core of Monstro’s product.
•
Design modeling and reasoning systems that meet the correctness and explainability requirements of financial services — where every recommendation needs to be traceable and defensible
•
Build internal applications and platforms (Python/React) that enable domain experts and engineers to author, validate, and deploy AI-powered analysis at scale
•
Document your decisions, ensure sufficient test coverage and generate AI native artifacts to share your work with others
•
Own distributed backend infrastructure: event-driven workers, job pipelines, and multi-stage processing systems that deliver AI outputs reliably under load
•
Establish patterns for AI output validation and quality assurance — including automated evaluation pipelines, hallucination detection, and compliance guardrails
•
Drive technical decisions across teams: schema design, API contracts, system boundaries, and service architecture
•
Contribute to full stack application development
What We’re Looking For
•
Hands-on experience designing, building, and shipping production software systems using AI development tools, especially AI-powered software
•
Deep curiosity about where AI-native software is heading — you actively explore emerging capabilities and are excited to help define how they should be applied in real production systems, not just follow established patterns.
•
Strong software engineering skills and experience with a demonstrated track record contributing to best practices application architecture
•
Python expertise — async services, type-safe code, and systems that scale
•
Strong distributed systems fundamentals: event-driven architectures, message queues, job state machines, and worker patterns
•
Relational database fluency and an instinct for data modeling
•
Full-stack range — you can build product-quality React/TypeScript UIs when the problem calls for it
Preferred but not required
•
Hands-on experience with AI/ML systems — agent architectures, LLM integration, model evaluation, or AI pipelines in production
•
Opinionated about how AI systems should be tested, evaluated, and monitored in production
•
Experience designing multi-agent systems, agentic workflows, or AI orchestration layers
•
Data engineering experience developing data pipelines handling big data
•
Experience contributing to cloud infrastructure using infrastructure as code
•
Background in quantitative finance, financial planning, or wealth management technology
•
Experience leading technical teams or acting as a force multiplier across engineering
•
Experience building AI systems in regulated industries (financial services, healthcare, legal) or with compliance, auditability, or explainability requirements

A Note on Interviewing: We sometimes use AI note-takers to help us transcribe interview notes, so we can be more present in your interview. If you’d like to opt out of us using automatic transcribers, please note this in the free text field in your application; otherwise we’ll take your application as confirmation that you’re happy for us to use note-takers (whether added to video calls or in the background).
Ready to Build With Us?
The standard is simple: do great work, own the outcome, communicate with purpose, move with urgency, raise the level. If that sounds like you, we’d love to hear from you.
