Your opportunity

At Schwab, you’re empowered to make an impact on your career. Here, innovative thought meets creative problem solving, helping us “challenge the status quo” and transform the finance industry together.

We believe in the importance of in-office collaboration and fully intend for the selected candidate for this role to work on site in the specified location(s).

The Trading Technology Services team is responsible for managing the trade entry and executions. The entire trade movement and corrections also is maintained by this team using a sophisticated portal. This position is for the portal development in Angular front end and C# backend.

Responsibilities:

+ Design and govern high-performance .NET 8 applications, services, and APIs using async/await, structured concurrency (Tasks, Channels, Pipelines), and lock-free patterns to maximize throughput and minimize latency under burst load. Experience coding multi-threaded applications

+ Design scalable, secure .NET solutions using SOLID, clean architecture, and domain-driven patterns. Translates requirements into clear API contracts, performance targets, and testable specs.

+ **Event & integration patterns:** Implementation of resilient pub/sub, back pressure controls (reactive buffering / flow control), replay mechanisms (event sourcing / audit streams), idempotency safeguards (dedupe stores, hash keys), contract/version management.

+ **Testing excellence:** Authoring high-value unit test suites (xUnit/NUnit) with coverage thresholds enforced in CI; behavior-driven test automation using Reqnroll/SpecFlow + Gherkin for regression and complex business rule validation; test data orchestration & deterministic test isolation.

+ **Observability & logging:** Implementation of structured logging with correlation / causation IDs, OpenTelemetry tracing (custom spans, baggage, propagators), custom metrics aligned to SLIs/SLOs (latency percentiles, error budgets), log volume & retention cost optimization (sampling, aggregation).

+ **Performance engineering:** Performing systematic profiling (CPU, allocations, async/lock contention, heap fragmentation), enforcing latency budgets per component, conducting load / soak / spike / failure injection tests, creating repeatable benchmarking harnesses with statistically significant results.

+ **Reliability & quality:** Execution of chaos scenarios (timeout storms, partial dependency failure, network partition), graceful degradation feature toggles, automated rollback criteria (error rate / latency threshold triggers), resilience patterns (circuit breakers, bulkheads, hedging).

+ **Communication & leadership:**

+ Synthesizes complex architecture trade-offs (data stores, messaging patterns, latency vs cost) into clear decision briefs for fast alignment.

+ Facilitates blameless postmortems and turns findings into prioritized reliability/backlog items with measurable SLO impacts.

+ Orchestrates audience-specific communication (executive briefs, deep technical analyses, architecture visuals, narrative context) to align executives, product, and engineering on strategic priorities and trade-offs.

+ Uses data storytelling (metrics + business context) to secure investment in technical debt reduction and resiliency initiatives.

What you have

Required Qualifications

+ Deep experience building ultra-low-latency, high-throughput trading or market data systems (FinTech / capital markets).

+ Builds .NET 8 services with structured logging, health/readiness endpoints, and coordinated handoffs to improve production support and lower Mean Time to Repair (MTTR).

+ Extensive hands-on experience building high‑performance, distributed .NET solutions leveraging Aerospike and MongoDB for low‑latency, scalable data access.

+ Extensive hands-on experience implementing high‑throughput messaging patterns in .NET using IBM MQ (transactional, exactly-once semantics) and Apache Kafka (event streaming, partitioning, consumer group optimization).

+ Implements data classification, retention, encryption (in transit/at rest), and audit trails to enforce legal and ethical compliance.

+ Applies resilience patterns (timeouts, retries, circuit breakers) and fallback strategies to improve incident response and reduce failure impact.

+ Establishes shift-left test suites (unit, integration, performance, property-based) to raise coverage and protect product integrity.

+ Translates prioritized business requirements into technical backlogs using value/risk scoring to accelerate outcome delivery.

+ Integrates least privilege, secret management, secure pipelines, and vulnerability remediation workflows aligned to business security needs.

+ Delivers domain-driven, SOLID, evolvable designs mapped to measurable performance, reliability, and maintainability objectives.

+ Optimizes verification pipelines via parallelization, test impact analysis, and flaky test isolation to improve reliability and lead time.

+ Automates container/image packaging with provenance, progressive deployment (blue/green, canary), and rollback safeguards.

+ Designs horizontally scalable, cost-aware architectures using predictive capacity models and adaptive refactoring to sustain growth.

+ Bachelor’s degree in Computer Science or equivalent.

Preferred Qualifications

+ Aerospike: Proven hands-on expertise in data model optimization (set/bin design), secondary index and XDR tuning, benchmarking read/write latency at scale, hot key / hotspot mitigation (data distribution strategies), migration & upgrade impact analysis.

+ MongoDB: Hands-on production experience with high-concurrency schema design (document sizing, embedding vs referencing), sharding / re-sharding strategy execution, compound & TTL index lifecycle management, query plan / execution Stats analysis, performance baseline creation and regression detection.

+ SQL Server: Deep hands-on performance tuning (index selection & maintenance automation, filtered/indexed views, partitioning strategies, statistics management), query plan stability (parameter sniffing mitigation), lock/block/wait analysis (WAIT_STATS, deadlock graphs), large batch purge & archival patterns minimizing log growth and IO spikes.

+ Communication & leadership:

+ Leads design reviews emphasizing problem framing, risk surfacing, and documented rationale for chosen approaches.

+ Establishes pragmatic quality gates (coverage, mutation score, latency thresholds) while coaching autonomy over compliance.

+ Build trust through transparent risk communication, predictable follow-through, and ethical handling of sensitive data.
