About BolsterBiz

BolsterBiz helps US-based companies scale efficiently by building and managing high-quality teams in India across Software Engineering, Quality Engineering, SRE, Customer Support, Digital Marketing, and Data Analytics. We manage hiring, payroll, compliance, performance, and day-to-day operations, acting as an extension of our clients teams.

You'll work on high-availability systems that connect with financial institutions and payment processors, ensuring secure, compliant, and lightning-fast transactions. The work you do will directly impact our users ability to access their money instantly, earn meaningful rewards, and experience transparent, fee-free financial services.

You'll have the opportunity to work with modern technologies (including Rust microservices and event-driven systems) while shaping the next generation of inclusive, data-powered financial products. You'll design APIs and microservices that connect financial institutions, payment processors, and data platforms, all while ensuring reliability and privacy at scale.

You'll be a great fit for the role if:

•     You care deeply about operational quality and enjoy ensuring customer-impacting workflows are handled accurately and consistently.

•     You have experience executing and improving runbook-driven processes, and can spot gaps or edge cases that need better documentation or tooling.

•     You're strong at bug investigation, validating issues, confirming repeatability, and grouping related problems to reduce noise.

•     You're comfortable making small, targeted improvements, including light code changes, minor data fixes, or internal reporting enhancements.

•     You communicate clearly and collaborate well across CX, Product, and Engineering in a feedback-driven environment.

Job Responsibilities

•     Production Incident Support (70%) — Working closely with the Head of Customer Support to investigate, troubleshoot, and resolve production incidents impacting customers, including the runbook-based CX support and bug investigation work detailed below.

•     API / Microservice Development (30%) — Building and enhancing backend systems, including designing and shipping APIs and microservices that connect financial institutions, payment processors, and data platforms.

What your day-to-day will look like:

Runbook-based CX support

•     Provide runbook-based support for Customer Experience (CX) tickets, handling common operational workflows and ensuring timely resolution of user issues, including:

○    Advance failure remediation and investigation

○    Repayment issues and troubleshooting

○    Advance and repayment confirmations for users and internal teams

○    Account deletion requests and related follow-up actions

○    Collaborate and communicate with both CX and Engineering teams

Bug investigation

•     Perform initial investigation on reported bugs to help streamline engineering efforts by:

○    Validating bug reports and confirming reproducibility

○    Identifying root patterns and grouping related issues (e.g., debit card failures, Plaid linking problems, repayment errors)

○    Providing clear, actionable context to engineering teams for deeper fixes

Internal tooling and reporting

•     Support internal tooling and internal user-facing features by:

○    Implementing reporting or visibility enhancements (such as user state indicators or collection attempt history)

○    Addressing bugs, primarily related to data accuracy, user experience, and display issues

•     Assist with reporting and data requests across the organization:

○    Generate user counts and performance metrics for investigations, audits, or validation efforts

○    Execute one-off data operations such as mass user blocking, PII cleanup or corrections, and targeted data fixes

Technical Requirements

•     Programming Language — Experience writing excellent production code in Node.js (JavaScript/TypeScript), Rust, or similar.

•     Database — Experience with advanced queries using MySQL, Postgres, SpannerDB, or similar, since investigations will require digging into raw data.

•     Architecture — Experience implementing Microservice architecture, Event-driven architecture, or similar — at least 4–5 years total (or 2 years Microservices + 2 years API development).

•     API Layer — Experience building GraphQL, gRPC, and REST APIs.

•     Infrastructure — Working knowledge of Cloud (GCP/AWS), Docker, Terraform, Kubernetes, Kafka, S3/GCS Buckets, Artifactory, BigQuery/Data Lake, etc.

•     APM — Working knowledge of application monitoring and logging systems like Grafana/Prometheus, New Relic, Kibana, Datadog, or similar.

•     BI Tools — Experience with BI tools like Looker, Tableau, etc.

•     Domain — Fintech experience preferred.

Preferred Qualifications

•     8+ years of experience in software engineering, quality engineering, SDET, or technical operations supporting production systems.

•     Strong focus on operational quality and correctness in customer-impacting workflows, particularly in financial or regulated domains.

•     Comfort executing and improving runbook-driven operational processes, including identifying gaps, edge cases, and documentation issues.

•     Proven ability to investigate and validate production issues, including reproduction, confirmation, and defect clustering to reduce noise.

•     Ability to make small, scoped improvements to existing systems (e.g., test fixes, configuration changes, minor data corrections, or internal tooling enhancements).

•     Working knowledge of logs, metrics, and basic service observability for debugging and validation.

•     Clear, effective collaboration with Customer Experience, Product, and Engineering teams to close feedback loops.
