Top Software Engineer Jobs

An early-career software engineering resident will build and deploy production services, use AI tools to accelerate development, improve system performance, and collaborate with product, design, and engineering teams. The 18-week program requires full-time, in-office work in New York City and offers potential full-time employment after completion. Residents are expected to ship a real contribution, apply strong computer science fundamentals, and work effectively in a fast-paced environment.

Build a greenfield, low-latency algorithmic execution platform in C++. Responsibilities include developing FIX gateways, exchange market data feed handlers, venue connectivity, pre-trade risk controls, platform infrastructure, audit logging, and algorithmic strategy migration. The role requires optimizing critical paths for microsecond-level performance while integrating U.S. exchanges and dark venues. Future work includes multi-asset execution, research and backtesting, and international market expansion.

Build and maintain reproducible research infrastructure for evaluating digital-twin and large language model systems. Responsibilities include automating experiments, implementing deterministic measurement pipelines, managing versioned datasets and human-participant data, maintaining research-production alignment, monitoring evaluation validity and compute costs, and supporting documented coding workflows. The role requires strong Python, data pipeline, cloud, concurrency, machine learning, and software engineering skills, with preferred experience in LLM systems, model fine-tuning, inference serving, experiment tracking, and generative agents.

Build software simulators modeling the National Airspace System, including aircraft trajectories, weather, air traffic control, and pilot behavior. Design simulation infrastructure and physics-based models using discrete-time simulation, statistics, algorithms, and Monte Carlo analysis. Develop mission-critical software for aviation decision-support systems and collaborate across teams in a safety-critical environment.

Build and evolve scalable, performant software services supporting production AI systems. Responsibilities include writing quality code, designing cloud-neutral microservices, optimizing and deploying AI models, contributing to architecture and design discussions, leading the software development lifecycle, mentoring engineers, and collaborating cross-functionally. The role requires expertise in Go or another major programming language, Python, DevOps technologies, cloud architecture, databases, and scalable service development.

Improve Radar’s geocoding and autocomplete systems at massive scale by enhancing query understanding, retrieval, ranking, relevance, and location-data quality. Build automated data pipelines, integrate messy global sources, and apply ML or LLMs where useful. Work across Scala and Python data pipelines, Rust search and serving systems, and customer-facing product improvements while participating in on-call support.

Build, configure, administer, and maintain Salesforce solutions supporting go-to-market teams. Translate business requirements into scalable technical designs, manage users and access controls, troubleshoot production issues, support integrations and multi-org initiatives, document configurations, and participate in testing, quality assurance, change management, and SOX-compliant releases. Collaborate with cross-functional stakeholders and external partners while communicating technical information and project risks clearly.

Lead the design, development, and operation of integrations and API products. Establish standards for API contracts, authentication, authorization, versioning, reliability, observability, documentation, and developer experience. Drive cross-team system architecture, production readiness, scalability, security, and resilience while mentoring engineers and aligning technical decisions with product and business goals.

Leads the Payments Platform engineering organization, owning strategy, architecture, roadmap, delivery, and operational health for global payment processing, routing, settlement, reconciliation, and partner integrations. Manages Engineering Managers and senior technical talent, guides scalable and reliable distributed-system architecture, and partners with Product, Commercial, Risk, Compliance, and regional engineering leaders to support growth and regulatory requirements.

Leads architecture, development, testing, debugging, profiling, and optimization of SDK power-management software for low-power ARM Cortex-M MCUs. Responsibilities include clock and memory management, low-power modes, RTOS ports, power modeling, system-level optimization, technical reviews, cross-functional issue resolution, and mentoring. The role requires hands-on embedded firmware development and technical leadership across hardware, software, validation, and vendor teams.
