A Junior Python Developer is an entry-level software developer who specializes in writing, testing, and maintaining code using the Python programming language. They typically work under the guidance of senior developers and assist in building applications, fixing bugs, and improving performance. Their responsibilities may include writing scripts, working with databases, and integrating third-party services. Strong problem-solving skills, knowledge of Python frameworks like Django or Flask, and familiarity with version control systems like Git are often required. Junior developers are expected to learn quickly and contribute to the development team while gaining hands-on experience.
To thrive as a Junior Python Developer, you need a solid foundation in Python programming, an understanding of computer science fundamentals, and often a relevant degree or coursework. Familiarity with version control systems like Git, basic experience with web frameworks such as Flask or Django, and knowledge of databases are commonly expected, while certifications like PCEP can be advantageous. Attention to detail, a willingness to learn, effective problem-solving, and strong communication skills are essential soft skills for this role. These competencies ensure you can contribute efficiently to software development projects, adapt to new challenges, and collaborate well within a development team.
As a Junior Python Developer, your daily tasks may include writing and testing code, fixing bugs, and participating in code reviews alongside more experienced developers. You'll often work on modules or features under the guidance of senior team members, attend stand-up meetings, and update project documentation as needed. Collaboration with frontend developers, QA testers, and project managers is common, especially when integrating systems or implementing new features. Over time, you can expect to take on more complex tasks and gradually build your expertise through mentorship and hands-on project work.

Senior Python Engineer Mainframe (DB2/JCL) Design build Python on z/OS (USS): Develop CLI tools, services, and batch utilities that run natively on z/OS Unix System Services (USS) or orchestrate mainframe jobs from distributed hosts.
Batch orchestration: Create and maintain JCL (PROCs, symbolics, condition codes, GDGs) and integrate with enterprise schedulers (e.g., Control-M, CA-7). Implement robust restart/recovery and step-level error handling.
DB2 for z/OS engineering: Write and tune SQL; implement stored procedures; design schemas and indexes; use EXPLAIN, RUNSTATS, and utilities (LOAD/UNLOAD/REORG) to hit SLAs.
PythonDB2 integration: Connect via ibm_db/CLI/ODBC and optimize connection pooling, cursor usage, and transaction boundaries for high-throughput workloads.
Data processing pipelines (plus): Build high-volume ETL/ELT flows with Python (e.g., pandas, PyArrow, Dask) and efficient I/O (binary formats, streaming, chunking).
Job submission automation: Submit and monitor jobs via SDSF, z/OSMF REST APIs, or Zowe CLI; parse JES output; automate handoffs and notifications.
Reliability observability: Implement structured logging, metrics, and tracing; integrate with enterprise monitoring (e.g., Splunk, ELK).
Testing CI/CD: Enforce unit/integration tests (pytest), code reviews, linting/type hints (flake8/ruff/mypy), packaging, and CI/CD (e.g., Jenkins, GitLab).
Security compliance: Follow RACF/Top Secret/ACF2 controls, least privilege, and data governance for PII/PCI/SOX environments.
Mentorship documentation: Coach engineers on Python + mainframe best practices; produce clear runbooks and architecture docs.
Required qualifications 8+ years professional Python (3.x) building reliable, performant production systems (CLIs, services, or batch).
Hands-on Python on the mainframe (must-have): Comfortable with z/OS USS, TSO/ISPF, SDSF, OMVS, dataset concepts (PS/PO, GDGs), code pages/EBCDIC vs ASCII, and file I/O nuances.
Mainframe DB2 expertise: Strong DB2 for z/OS (SQL tuning, indexing strategies, access paths, utilities, locking concurrency).
Familiar with SPUFI, DSNTEP2, IBM Data Studio (or equivalents).
Deep JCL proficiency:
PROCs, symbolic parms, condition codes, dataset allocation, DFSORT/ICETOOL, IDCAMS, and common utilities; experience wiring JCL into enterprise schedulers.
Scripting OS: Shell (sh/bash) on USS; comfort with dataset/file conversions, large file throughput, and job logs.
SDLC discipline: Git, trunk-based development, code reviews, tickets/change management (e.g., Jira/ServiceNow).
Excellent communicator with the ability to translate between mainframe, data, and app teams.
Data-processing Python: pandas, PyArrow, Dask;
memory/perf tuning for large datasets; binary formats (Parquet/Avro).
Automation toolchain:
Zowe CLI, z/OSMF REST, IBM Z Open Automation Utilities, Ansible for z/OS.
Integration: IBM MQ, CICS, Kafka/CDC (e.g., IBM Data Replication), REST/gRPC services bridging z/OS and distributed.
Performance engineering: SMF insights, buffer pool tuning (with DBAs), batch window optimization.
Refactoring legacy: Translating COBOL/PL/I batch logic to Python where appropriate; creating safe migration paths.
Distributed data engines: PySpark/Spark (for off-platform processing), Airflow.
Observability SRE: SLA/SLO design, incident response for nightly/weekly batch cycles.
Tools environment (illustrative) Mainframe: IBM z/OS 2.x, USS, TSO/ISPF, SDSF, RACF/Top Secret/ACF2 Data: DB2 12/13 for z/OS;
utilities (REORG/RUNSTATS/LOAD/UNLOAD) Python: 3.x, venv/poetry, ibm_db/ODBC, requests, pandas/PyArrow (as applicable)
Automation: Zowe CLI, z/OSMF APIs, Control-M/CA-7, Jenkins/GitLab CI Monitoring: Splunk/ELK, enterprise log aggregation Success metrics Batch SLAs consistently met; reduced average job elapsed time and rerun rates Measurable DB2 query/perf improvements (e.g., CPU, getpages, elapsed time) Increased automation coverage (job submission/monitoring, recovery) High test coverage and low change-failure rate across releases Education certification BS/MS in CS, EE, or equivalent experience
IBM Certified Database Admin DB2 for z/OS; IBM z/OS Associate/Professional; Control-M/CA-7 certifications
