About The Company
We are building the technology and support infrastructure to help people navigate complex loan-related challenges. Millions of borrowers struggle with overdue loans, multiple EMIs, persistent recovery calls, legal notices, and uncertainty about what to do next. We bring together technology, AI, data, and expert support to help customers understand their situation, take the right next steps, and work towards resolving their loan-related issues.
We are building a customer-first platform where complex financial problems can be handled through simple, guided, and technology-enabled experiences.
As an early-stage company, we operate with a strong bias towards ownership, speed, experimentation, and measurable outcomes. Every team member is expected to solve problems end-to-end, challenge assumptions, and turn ideas into execution.
What You Will Own
Own a service end to end - schema, API, deployment, dashboards, and alerts - rather than picking up tickets against someone else's design.
Make the failure cases boring : idempotency, retries, timeouts, dead-letter handling, and a reconciliation job that catches what all three miss.
Write design notes before large changes, and reviews that improve the code rather than approve it.
Debug production with logs, metrics, and traces - and fix the cause, not the symptom.
Skills And Experience
Required :
5+ years building backend systems that real users depend on, with strong fundamentals in at least one of Rust, Go, Java, Python or Node.
You have worked on a system where work crosses service boundaries and some of it fails - queues or streams, retries and idempotency, caching and invalidation, a migration done without downtime.
SQL and NoSQL : solid relational skills - schema design, indexing, transactions, reading a query plan, fixing a slow query without reaching for a cache - plus working use of at least one non-relational store.
AWS : you have deployed and debugged your own services on AWS. ECS or EKS, RDS, S3, SQS or SNS, IAM, and CloudWatch or equivalent.
REST API design that survives contact with other teams : versioning, error semantics, pagination, and auth.
Git, CI, and testing habits you do not need reminding about.
Writing clear enough that a short design note settles a disagreement.
What We're Looking For
Strong ownership and ability to independently drive work from problem identification to execution.
Ability to work in a fast-paced environment with changing priorities.
Strong analytical and problem-solving skills.
Clear communication and strong stakeholder-management skills.
Bias towards action and ability to execute with limited supervision.
Comfort working with data and using it to make decisions - here, that means latency, error rates, and queue depth as readily as product numbers.
Ability to identify problems, challenge existing approaches, and propose practical solutions.
Strong attention to detail and a high bar for execution.
Nice To Have
Payments, lending, or banking backend work - UPI, NPCI rails, KYC, credit bureaus, collections, or a ledger you had to keep balanced.
Event-driven systems in production : Kafka, SQS, Temporal, CDC, or the transactional outbox pattern.
Rust, or a genuine willingness to learn it - our core service is Rust on ECS.
LLM-backed features that reached production, with evaluation and cost control rather than a demo.
Open-source contributions, a side project people actually use, or a competitive programming record.
Early-stage startup experience, where the requirements changed under you and you shipped anyway.
