Project Description:
The project is focused on improving the security, release reliability, maintainability, and operational resilience of business-critical banking applications.

Forward Deployed Engineers will conduct targeted, hands-on engagements with development teams that are facing challenges with vulnerability remediation, automated testing, legacy technology, production stability, or achieving a safe and rapid release cadence.

The role combines senior software engineering, DevOps, SRE, test automation, application security, and legacy modernization. Approximately 70% of the work involves hands-on coding and configuration.

The technical scope includes building effective automated test suites, remediating security vulnerabilities, performing dependency and reachability analysis, upgrading Java and NPM runtimes, modernizing Spring and legacy middleware applications, improving CI/CD pipelines, containerizing applications, automating deployments, and introducing standard observability and resilience patterns.

The Expert FDE is expected to lead complex engagements, work directly with development and client stakeholders, define the technical remediation approach, implement critical changes personally, and enable client teams to maintain the improved engineering practices.
Responsibilities:
– Lead targeted technical engagements addressing security, testing, release, resilience, and legacy technology challenges with development teams.
– Assess application code, dependencies, runtime environment, test coverage, deployment architecture, CI/CD pipelines, observability, and operational risks.
– Write, debug, review, and enhance production-quality code and configuration throughout engagements.
– Define and implement practical modernization and remediation plans with clear priorities, dependencies, risks, and measurable outcomes.
– Develop or improve unit, integration, component, contract, and deployment smoke tests using Test-Driven Development practices.
– Select appropriate automation-testing approaches per application and drive implementation, including the use of AI coding assistance.
– Source suitable test data and implement secure data masking for lower environments.
– Conduct vulnerability triage, root-cause and dependency reachability analyses, remediation prioritization, secure code changes, and regression testing.
– Upgrade Java, JVM, NPM, Spring, open-source libraries, internal dependencies, installed software, base images, and operating systems to supported versions.
– Establish sustainable dependency-management processes with continuous library updates using Renovate or equivalent tools.
– Modernize legacy applications and middleware stacks, including those deployed on WebSphere or WebLogic.
– Containerize applications using Docker and support deployment to OpenShift.

– Automate database changes using Liquibase or equivalent migration tools.
– Automate installed software and environment changes using Ansible or equivalent configuration management tools.
– Implement secure coding patterns, secrets management, authentication, authorization, and least-privilege controls.
– Introduce standard observability patterns, including structured logging, application metrics, tracing, dashboards, alerting, and actionable health checks.
– Enhance exception handling, operational diagnostics, rollback procedures, and production-validation controls.
– Design or improve resilient deployment architectures, including hot-hot cross-datacenter deployments where required.
– Lead technical workshops and effectively communicate technical decisions, risks, blockers, trade-offs, and progress to engineering, security, architecture, operations, project management, and stakeholders.
– Provide technical leadership through code reviews, coaching, reusable standards, documentation, and knowledge transfer to development teams.
– Take ownership from initial assessment through implementation, production deployment, stabilization, and handover.

У форматі forward-deployed ти будеш залучений до роботи з бізнесом над конкретними ініціативами, зберігаючи зв'язок із центральною технічною командою. Команда, ймовірно, зростатиме разом із попитом на AI в операційних компаніях.
Культура:
Ми дотримуємося високих стандартів у технологічній індустрії та постійно розвиваємося. Кожен член команди має можливість впливати на продукт, компанію, процеси й власний професійний розвиток.

Обирати моделі (Gemini, Claude, GPT, менші або спеціалізовані) під конкретний use case і уникати залежності від одного провайдера;
Тримати критичні розрахунки й операційні правила детермінованими, а LLM використовувати для класифікації, інтерпретації, узагальнення та аналізу, з механізмами валідації та human review;
Працювати з Data Engineers: визначати вимоги до даних і структуру data products та реалізовувати прикладний та AI-шари, що їх споживають;
Підтримувати автоматизацію фінансів і податків: підготовка US tax returns, global minimum tax, country-by-country reporting, консолідація даних між юридичними особами;
Будувати класифікацію документів та AI-assisted аналітику: порівняння результатів з історичними даними, виявлення аномалій, root-cause аналіз;
Допомагати стейкхолдерам формулювати реалістичні та вимірні AI use cases і формувати перевикористовувані патерни для Data & AI функції.
