About The Position

BDR Solutions LLC is seeking a Senior ALC Developer to serve as a Key Personnel position on an IRS MFRA Branch task order. IBM Assembler Language Coding (ALC) expertise is among the rarest skills in the federal IT workforce. This individual will serve as the technical authority for all ALC/assembler components within MFRA Branch systems, providing production O&M support and implementing ALC-side legislative changes. The role requires deep expertise in IBM mainframe assembly programming, AEV JCL, and the full IBM mainframe toolchain, and the ability to work within IRS's rigorous production control processes (PECP, Endevor, OneSDLC) from day one.

Requirements

8+ years IBM Assembler Language Coding (ALC) — mainframe assembly programming, structured programming in assembler
AEV JCL and standard IBM JCL — job stream design, modification, testing, and production scheduling
VSAM — file design, management, copybooks, panels, skeleton PROCS
IBM File Manager — mainframe file inspection, editing, and management
IBM Debugger — interactive debugging of ALC programs in DEV and QA environments
IBM Suite — full mainframe toolchain fluency
Endevor — source code management and production transmittal process
IBM ELM Suite (DOORS Next, IBM ETM, Jira) — requirements management and test management
PECP (Production Environment Control Process) Guidelines compliance
Knowledge of IBM mainframe architecture — z/OS, MVS, batch processing, CICS interaction from ALC layer
Strong debugging and root cause analysis skills in high-availability production environments

Nice To Haves

Direct IRS or Treasury mainframe ALC experience — especially MFRA, BMF, IMF, or tax processing applications
COBOL/CICS cross-training — ability to read and analyze COBOL programs that interact with ALC modules
Experience with high-availability Federal mainframe environments (IRS, SSA, Treasury, or equivalent)
Knowledge of CFOL command codes and Business Master File structure
Familiarity with DB2 interaction patterns from the ALC layer

Analyze, design, and implement ALC modifications for Filing Season, Mid-Year, and Tax-Year legislative changes
Perform AEV JCL modification, testing, and production deployment; manage JCL job streams for batch processing
Execute VSAM file management operations — VSAM structures, copybooks, panel definitions, skeleton PROCS
Triage and resolve P1/P2 ALC-related production incidents; perform root cause analysis and restore services to operational status
Use IBM File Manager and IBM Debugger for production defect investigation and code repair
Commit all source code to IBM ELM Suite before any Endevor transmittal; maintain complete artifact trail per OneSDLC/ELC requirements
Develop and maintain OneSDLC/ELC technical artifacts (SDP, SDSR, STP, COH, PRP) for ALC components
Transfer ALC system knowledge to IRS staff; document all ALC tribal knowledge into the team knowledge repository
Participate in Agile sprint ceremonies, CCB sessions, and technical reviews as the assembler/ALC technical authority
Support integration and interoperability between ALC components and COBOL/Java application layers
