About the role
Senior backend engineer responsible for owning and building Slope's backend systems powering embedded credit, payments, and underwriting; aims to turn ambiguous problems into reliable production systems with high ownership and collaboration.
Responsibilities
- Build and own production systems for underwriting, bank-data review, credit review workflows, portfolio monitoring.
- Create reusable infrastructure for evidence gathering, decisioning, monitoring, and human-in-the-loop review.
- Build internal tools that help the credit risk team review data, understand decisions, handle exceptions, and move faster without sacrificing correctness.
- Clearly communicate technical assumptions, tradeoffs, failure modes, system boundaries, and migration plans.
- Own ambiguous projects end-to-end: define the problem, propose a path, align across teams, ship production slices, measure, and iterate.
- Improve the reliability, latency, correctness of systems that directly affect credit decisions and customer experience.
Qualifications
- 5+ years of backend engineering experience, preferably in a fast-moving environment.
- Strong production backend experience with Node.js/TypeScript.
- Strong SQL skills and comfort working with relational databases, data warehouses, ETL/data pipelines, and messy real-world data.
- Experience designing APIs, services, jobs, data models, and contracts that other teams depend on.
- Experience in payments infrastructure.
- Track record of shipping systems where correctness, reliability, and operational clarity matter.
- High agency and proactive: you do not need fully specified tickets, and you know how to create clarity when the problem is vague.
- Strong written and verbal communication. You can explain tradeoffs, and failure modes.
- Product judgment for internal users. You care whether the system actually improves underwriting decisions and workflows, not just whether the code shipped.
- Experience with AWS, Postgres, Snowflake, queues, async jobs, observability tooling, and third-party financial APIs.
- Excitement around building AI-native infrastructure and agentic workflows, both within the engineering team as well as broader credit and data science teams.
- Excited to experiment with AI tools.
- Strong plus: Startup experience, especially in a high-ownership environment.
