Overview
Thank you for considering IT Concepts dba Kentro , where innovation drives opportunity and collaboration leads to success. Our dynamic community of experts is fully committed to advancing our customers' missions, fostering professional growth, and making a positive impact on our communities.
By joining our supportive community, you will find that Kentro is dedicated to your personal and professional development. Together, we can drive meaningful change, spark innovation, and achieve extraordinary milestones.
Kentro is hiring a Back-End Developer IV to serve as lead back-end developer on the Federal Aviation Administration’s (FAA) Accelerated Transformation of Legacy Applications and Systems (ATLAS) program — one of the largest civilian IT modernization efforts in the federal government. ATLAS covers a mission-support portfolio of more than 200 applications and roughly 3,000 databases, moving the agency off legacy sustainment and onto cloud-native architectures, automated workflows, DevSecOps delivery, and integrated AI capability.
In this role you translate portfolio architecture into server-side engineering patterns that back-end teams across the portfolio build against. You bring mastery of multiple back-end technologies, messaging systems, and integration patterns, and you apply it where the work is hardest: decomposing legacy monoliths, untangling point-to-point integrations built over decades, and standing up the enterprise APIs and services that replace them.
You lead complex system integrations, design portfolio and application service/API layers in alignment with the enterprise integration and API strategy, drive microservices adoption as a disciplined practice rather than a default, and provide technical leadership for large-scale back-end transformation across multiple delivery teams.
Location: Remote - This position can be performed remotely within the United States and will support Eastern Time working hours.
Compensation Range: The anticipated base salary range for this position is $149,000–$165,000 annually and reflects Kentro ’s good-faith expectations at the time of posting. Final compensation is determined based on the role’s requirements, relevant skills, experience, education, certifications, work location, applicable security clearance requirements, market conditions, internal equity, and contract requirements.
This Job Description reflects the primary duties of the role; however, it is not intended to be all‑inclusive. Team members may be asked to take on additional responsibilities in alignment with customer expectations, business needs, and Kentro ’s culture of collaboration and adaptability.
This position is contingent upon contract award*
Responsibilities
Define and implement server-side engineering patterns within established enterprise architecture and platform standards: runtime platforms, frameworks, service boundaries, data access patterns, and reusable service conventions
Establish and maintain back-end implementation patterns — microservices, event-driven, API-first, domain decomposition — and apply the architectural criteria that determine when each is the right call
Lead complex system integrations across legacy and modernized systems, including protocol translation, data reconciliation, and cutover sequencing on systems that cannot go down
Design portfolio and application service/API layers in alignment with the enterprise API and integration strategy: RESTful and event-based interfaces, API contracts and versioning, gateway integration, authentication and authorization patterns, and developer-facing documentation
Architect and implement messaging and streaming infrastructure (Kafka, RabbitMQ, ActiveMQ, or cloud-native equivalents), including delivery guarantees, idempotency, ordering, and failure handling
Design the serverless and event-driven processing built around that infrastructure — AWS Lambda, Azure Functions, or equivalent for ingestion, transformation, and event handling — and determine where serverless is the right fit against containerized services on cost, latency, and sustainment grounds
Drive decomposition of legacy monoliths into services: define bounded contexts, sequence the strangler-pattern migration, and manage the interim state where old and new run side by side
Lead database modernization work on the back end — schema evolution, data migration, dual-write and sync strategies, and the transition off legacy data stores
Set and enforce back-end engineering standards: coding standards, service templates, error handling, observability, resilience patterns, and performance budgets
Own non-functional outcomes for back-end services: availability, latency, throughput, scalability, and cost efficiency in a cloud environment
Integrate security into back-end design — secrets management, encryption in transit and at rest, least-privilege service identity, and controls aligned to FISMA, NIST SP 800-53, and applicable FAA and DOT policy
Build and maintain the reusable back-end assets that make a modernization factory model work: service scaffolds, shared libraries, integration accelerators, and reference implementations
Provide technical leadership, design review, and code review to back-end engineers across multiple teams; mentor mid-level and senior developers
Partner with enterprise architecture, front-end, data, and cybersecurity leads to ensure back-end designs fit the target-state architecture
Have the ability to write production code on the highest-complexity components as necessary — this is a hands-on lead role, not a purely advisory one
Qualifications
Bachelor's degree in Computer Science, Software Engineering, Information Systems, or a related technical discipline 8–10 years of progressive back-end development experience, including demonstrated technical leadership across multiple teams or a large system Expert-level proficiency in one or more major server-side stacks, with working command of a second (e.g., Java/Spring Boot, .NET/C#, Python, Node.js/TypeScript, Go) Deep experience designing and operating enterprise APIs: REST, API contracts and versioning, gateway and management tooling, and API security patterns
Hands-on expertise with messaging and event-driven systems (Kafka, RabbitMQ, ActiveMQ, SQS/SNS, or equivalent), including production experience with delivery semantics and failure modes
Proven experience leading complex system integrations across heterogeneous legacy and modern systems
Demonstrated experience decomposing monolithic applications into microservices, including the migration strategy — not just greenfield service development
Strong database expertise across relational and non-relational stores: data modeling, query performance, transactions, and large-scale data migration
Cloud-native back-end experience in a major cloud environment (AWS, Azure, or GCP), including containers, orchestration, and managed services
Practical DevSecOps experience: CI/CD, infrastructure as code, automated testing, and observability instrumented into services
Ability to set standards other teams adopt, and to communicate technical trade-offs to program leadership and government stakeholders
Experience implementing observability, resilience, and performance engineering for distributed services, including tracing, metrics, fault handling, and capacity/performance testing
Experience implementing shared engineering standards and reference patterns across multiple delivery teams
Exceptional communication and executive presence; able to advise senior government and corporate stakeholders and to justify architectural decisions
Working proficiency with approved AI-assisted development tools for code analysis, refactoring, test generation, and documentation
Preferred Qualifications:
Experience supporting FAA, DOT, or comparable federal civilian modernization programs
Experience modernizing mainframe or COBOL-era back ends, or integrating with them during transition
Specification-first API development using OpenAPI, including contract-driven design, generated clients and servers, and automated contract testing
Production experience designing and operating GraphQL APIs, including schema design, federation, resolver performance, and query cost control
Experience building Model Context Protocol (MCP) servers or comparable interfaces that expose enterprise services and data to AI systems and agents
Hands-on experience with NoSQL data stores — document databases (MongoDB, DynamoDB, Cosmos DB) and graph databases (Neo4j, Neptune, or equivalent) — including knowing when each is the right choice over a relational store
Large-scale database modernization experience (Oracle, SQL Server, or mainframe data stores to cloud-native or open-source targets)
Experience with service mesh, distributed tracing, and advanced observability in a microservices estate
Familiarity with FAA enterprise architecture, security engineering, and Authority to Operate (ATO) processes
Experience applying AI/ML or automated code transformation tooling to back-end legacy modernization
Relevant certifications: AWS or Azure Solutions Architect / Developer, Kubernetes (CKA/CKAD), or equivalent
Prior experience in a modernization factory, delivery center, or platform engineering organization
Clearance Requirement:
US Citizen
Existing FAA suitability determination or transferable federal background investigation strongly preferred
