Having recently announced our $45m series B, now couldn't be a better time to join!
The role
We're hiring a Senior Software Engineer to help build something brand new: Cryptio's Digital Assets Lending Marketplace. This is 0-1. You'll be building a high stakes financial product from the ground up, the kind that handles real money, real loans, and real consequences. Think loan creation, repayments, margin calls, liquidations, collateral releases, and marketplace execution. Get it right and we change how institutional crypto lending works. Get it wrong and someone's missing money. So, you know, no pressure. You’ll work closely with Product, Engineering, Risk, Operations, Compliance, and Leadership to shape the foundations of a platform that institutional customers will trust with serious assets. Correctness, reliability, and operational safety are everything here. If you've built complex production systems in financial services, trading, payments, custody, or settlement, and you love the idea of working on something where engineering quality genuinely matters, this is your kind of role.
Key technologies
- Rust
- Modern backend systems
- APIs
- Event‑driven architectures
- Distributed systems
What you’ll do
- Design and ship the core services behind our new Loan Marketplace
- Build the workflows that power loan disbursements, repayments, margin calls, liquidations, and collateral releases
- Plug into custodians, market data providers, and other financial infrastructure
- Build guardrails that make unsafe states genuinely hard to reach (state machines, validation, audit trails, reconciliation)
- Write tests that catch the scary stuff: integration, property based, simulations, fuzzing
- Own systems end to end, from first sketch to running in production with proper observability and runbooks
- Raise the bar through strong design, thoughtful code reviews, and mentoring other engineers
- Partner with Product, Ops, and Compliance to make sure the product is safe to ship and operate
We're looking for someone who
- Has 7+ years of software engineering experience, with strong backend or systems chops
- Has built complex production systems with real business impact
- Has worked on high stakes systems: financial, infrastructure, or anything mission critical
- Deeply gets concurrency, race conditions, distributed systems, idempotency, ordering, and partial failure
- Has a strong testing and correctness mindset
- Can design safe state transitions, audit trails, and reconciliation flows
- Owns technical design even when the product is messy and undefined
- Has Rust experience, or strong evidence they can pick it up fast
- Writes and talks clearly about complex trade offs
- Mentors others and lifts the standard around them
Bonus points if you’ve worked on
- Financial systems (trading, payments, settlement, custody, lending) and the concepts that come with them
- Integrations with custodians, exchanges, banks, or market data providers
- Production Rust, or advanced testing like simulations, fuzzing, or formal modelling
- Crypto or enterprise financial software
Why you’ll love this role
- Build a brand new financial product from scratch, the kind that genuinely matters
- Work on hard problems where engineering quality is the product
- Help shape how institutional crypto lending actually works
- Tackle technical challenges at the crossroads of crypto, fintech, lending, and enterprise software
- Work alongside a senior team that cares about getting things right
- Strong internal mobility and growth as we scale
