Who you are

- 5+ years of software engineering experience building and operating backend systems in production

- Know Python (our main stack), though we're open to strong candidates from other OO backgrounds

- Experience with AWS and serverless technologies (Lambda, Step Functions), asynchronous workflows, and cloud environments

- Strong knowledge of relational databases and their performance tuning, ideally PostgreSQL

- Mastery of software development fundamentals: system design, debugging, testing, and problem-solving

- Experience building external-facing APIs or designing integrations with third-party systems

- You take full ownership of your work and drive projects to completion with minimal oversight

- You communicate proactively: surfacing blockers, asking the right questions, keeping stakeholders in the loop

- You thrive on experimentation: comfortable testing ideas, measuring results, and iterating quickly on problems no one has solved before

- You're excited by problems others are struggling with

- Experience working with LLMs in production and an understanding of what it takes to deploy them at scale

- Experience with document pipelines and processing large amounts of data

- Experience with distributed systems
- Experience in insurance, fintech, or another data-heavy regulated domain

What the job involves

- We're looking for strong backend engineers who love building reliable systems around fragmented, high-value data

- Kalepa's platform ingests billions of highly unstructured data points every day, extracts precise information from them, and surfaces the insights insurers rely on for high-stakes decisions





- As a Senior Backend Engineer, you'll own strategically significant, complex pieces of that system with minimal oversight: the services, data models, pipelines, and evals at its center, and the external-facing APIs that power our customers' core workflows

- You'll work at the intersection of AI and backend engineering, on a problem the industry hasn't solved effectively yet

- You'll join a high-ownership team responsible for some of Kalepa's most business-critical infrastructure, and you'll help the engineers around you do their best work

- Lead the scoping, design, and delivery of complex backend systems in Python on AWS: services, data models, and asynchronous pipelines

- Build and scale LLM-based systems that process large volumes of unstructured documents and data with precision and explainability

- Design external-facing APIs and integrations with third-party systems that customers depend on

- Own database and query performance as data volume grows; proactively manage technical debt

- Contribute to architectural discussions and decisions across the entire product, and iterate with teams to modify and prioritize within the development effort

- Accurately estimate your work, consistently meet deadlines, and help others estimate theirs

- Take a leading role in incident and bug resolution; be the strong debugger others turn to

- Lead the adoption of best practices for development, testing, and deployment

- Mentor other engineers through code review, pairing, and design feedback

- Use AI tooling deliberately to multiply your own output and quality
