Open Positions
Your Next Career Move Starts Here
We are actively hiring across engineering, cloud operations, and data. These are not support roles — you will own outcomes, work directly with enterprise clients, and build systems that run at scale.
Application Security Engineer
Strengthen our clients' software delivery lifecycle by embedding security at every stage — from code commit to cloud deployment. You will perform application penetration testing, implement and manage SAST/DAST scanning pipelines in GitHub, conduct Dynamic Security Assessment Testing (DSAT), and enforce security best practices across Azure cloud environments. This is a hands-on role where you own the security posture of production applications, work directly with development teams to remediate vulnerabilities, and build automated security gates into CI/CD workflows.
Requirements
- 3+ years of hands-on experience in application security, penetration testing, or security engineering
- Proficiency with SAST/DAST tools — SonarQube, Checkmarx, Snyk, OWASP ZAP, Burp Suite, or equivalent
- Experience with Azure cloud security — Azure Security Center, Azure Defender, Key Vault, NSGs, and identity management (Entra ID)
- Strong knowledge of GitHub Advanced Security features — code scanning, secret scanning, Dependabot, and security advisories
- Hands-on penetration testing experience for web applications and APIs (OWASP Top 10, SANS Top 25)
- Understanding of CI/CD security integration — embedding security gates in GitHub Actions, Azure DevOps, or similar pipelines
- Experience with vulnerability management, risk assessment, and remediation tracking
- Familiarity with compliance frameworks relevant to healthcare and financial services (HIPAA, SOC 2, PCI-DSS)
- Strong scripting skills (Python, Bash, or PowerShell) for security automation
- Excellent communication skills to articulate security findings and remediation guidance to development teams
Data Engineer – BI Migration & Analytics
Join our team to support a large-scale migration from SQL Server Reporting Services (SSRS) to Microsoft Power BI. This is a hands-on technical role requiring deep SQL and PL/SQL expertise to deconstruct complex stored procedures, optimize queries, and rebuild reporting logic in Power BI. Following the migration phase, you will transition into Databricks semantic layer development, contributing to a modern lakehouse analytics architecture.
Requirements
- 5+ years of hands-on experience in data engineering or business intelligence roles
- Expert-level SQL skills — complex joins, CTEs, window functions, performance tuning, and execution plan analysis
- Strong PL/SQL / T-SQL proficiency — ability to read, rewrite, and optimize stored procedures and functions
- Proven experience migrating SSRS reports to Power BI, including data model redesign and DAX authoring
- Solid understanding of Power BI Desktop, Power BI Service, and Power Query (M) transformation layer
- Experience working with relational databases such as SQL Server, Oracle, or PostgreSQL
- Working knowledge of Databricks, Delta Lake, or Apache Spark is a plus
- Familiarity with Azure Data Factory, Azure Synapse Analytics, or other Azure data services is a plus
Senior Java Developer
Build and maintain event-driven microservices on AWS using Java and Spring Boot, with Kafka for asynchronous messaging, PostgreSQL with connection pooling for persistent storage, and ElastiCache for low-latency caching. You will own your services end-to-end — writing clean, testable code, optimizing performance, and deploying to production. This is a hands-on individual contributor role where you will also participate in architectural discussions and contribute to design decisions that shape our backend platform.
Requirements
- 5+ years of backend development with Java and Spring Boot
- Hands-on experience with Apache Kafka and event-driven architecture patterns

- Proficiency with RESTful API design, microservices patterns, and distributed systems
- Solid understanding of caching strategies using Redis/ElastiCache for performance optimization
- Experience with CI/CD pipelines, Docker, and infrastructure-as-code practices
- Strong analytical and problem-solving skills with attention to system reliability
- Excellent collaboration and communication skills in cross-functional teams
- Familiarity with unit testing (JUnit, Mockito), integration testing, and code quality tools
Senior Full-Stack Developer
Own the full lifecycle of enterprise web applications serving healthcare and financial services clients. You will build performant APIs with Python and FastAPI on the backend, and deliver polished user experiences with Next.js and React on the frontend. This is a high-visibility role where you lead feature delivery from concept to production, mentor a growing engineering team, and collaborate directly with client stakeholders.
Requirements
- 5+ years of full-stack development experience
- Strong backend proficiency with Python and FastAPI (or Flask/Django)
- Solid frontend experience with React and Next.js, including SSR and API routes
- Experience with PostgreSQL or other relational databases

- Experience with CI/CD pipelines, Git workflows, and automated testing
- Excellent communication and client-facing skills
DevOps Engineer
Design and operate the CI/CD pipelines, Kubernetes clusters, and cloud infrastructure that power enterprise-grade applications. You will drive GitOps adoption, build internal developer platforms, and directly influence how engineering teams ship code. If you want to work on infrastructure that handles real production traffic at scale, this role delivers.
Requirements
- 3+ years in DevOps or SRE roles
- Proficiency with Kubernetes, Docker, Terraform
- Experience with AWS cloud services (ECS/EKS, EC2, S3, CloudWatch, IAM)
- Knowledge of GitOps tools (ArgoCD, Flux)

PostgreSQL Database Administrator
Take ownership of production PostgreSQL environments for enterprise clients in healthcare and finance. You will architect high-availability configurations, lead disaster recovery planning, and optimize performance for workloads where downtime is measured in dollars. This is a role with real accountability and direct business impact.
