Staff Backend Engineer – Python / SQL / Data-Intensive Systems

Position: Staff Backend Engineer – Python / SQL / Data-Intensive Systems
Location: Hyderabad
Work Mode: Hybrid
We are looking for a Senior Staff Backend Engineer to own the core computation services powering a data-intensive financial and operational platform. This is a hands-on technical leadership role focused on building correct, reproducible, traceable, and auditable computation systems not dashboards or LLM wrappers.
Role:
Own backend services performing complex financial and operational computations
Build reusable, configuration-driven computation components and rules engines
Design high-performance, set-based computation using advanced SQL
Ensure every result is reconcilable, reproducible, and traceable to source
Build configuration runtimes that enable new domains/use cases without bespoke code paths
Implement guardrails, audit logging, lineage, feature controls, and confidence signals
Design for multi-tenant, multi-cloud and customer-hosted deployments with strong isolation
Set engineering patterns, review designs and mentor backend engineers
Partner with Data, AI and Product teams to translate complex domain logic into scalable services
Technical Skills:
Python | SQL | Snowflake | PostgreSQL | Docker | Kubernetes | Terraform
Experience with configuration-driven/rules-engine architectures and large-scale data computation is highly valued.
Experience:
8+ years of backend engineering experience with significant Staff/Senior Staff-level ownership
Strong expertise in Python, Go, Java or similar backend technologies
Elite SQL skills — window functions, complex joins, data modeling and performance optimization
Proven experience building data-intensive, configuration-driven service architectures
Strong system design expertise across reliability, scalability, isolation and reproducibility
Deep focus on correctness, testing, traceability and auditability
Good to have Experience with financial/accounting systems, regulated environments, dbt, Snowflake, PostgreSQL, multi-tenant SaaS, customer-hosted platforms, ML/statistical workflows or LLM integrations.
You’ll own the engineering layer behind numbers that may sit alongside externally reported financials. Correctness is non-negotiable: every result must be explainable, reproducible and auditable.
We’re looking for a hands-on senior engineer who enjoys solving difficult backend, data and computation problems at scale.
