Sr. Software Engineer

IMMEDIATE JOINERS APPLY

Role Summary

We are seeking a Senior Software Engineer with 6–8 years of experience to take a technical leadership role across two critical initiatives: the Manufacturing Execution Platform Modernization project (architectural upgrade of a globally deployed Manufacturing Execution System for global manufacturing client across 11 sites) and the AI workflow automation platform (an AI-enabled digital workflow platform for SAP S/4HANA business process automation). You will own complex technical design decisions, lead implementation efforts, mentor junior developers, and work closely with the US-based architect to shape the overall system architecture.

This role requires deep .NET expertise, strong system design skills, and the ability to operate across the full stack — from database schema design and ORM architecture to API design, frontend architecture, security implementation, and deployment orchestration. You will be a key technical decision-maker as ATPL scales its team and product portfolio.

3. Key Responsibilities

Technical Leadership & Architecture

· Own end-to-end technical design for major features and work packages across both manufacturing execution platform and AI workflow automation projects.

· Make architectural decisions on framework upgrades (.NET 8 to .NET 10 LTS), ORM strategy (DevExpress XPO migration), UI framework migration (Windows Forms to Blazor), and messaging architecture (Akka.NET, RabbitMQ).

· Design the AI workflow automation platform architecture — three-layer model (Input/Extraction, Agentic Processing, Exception/Visibility), API gateway, workflow orchestration engine, and SAP integration layer.

· Define coding standards, review guidelines, and technical documentation expectations for the development team.

· Conduct code reviews and provide constructive technical feedback to ensure quality, security, and maintainability.

Manufacturing Execution Platform Modernization

· Lead the .NET 10.0 (LTS) upgrade across all manufacturing execution APIs and services — manage dependency upgrades (Akka.NET, DevExpress Universal, RabbitMQ client libraries) and ensure backward compatibility across 11 global sites.

· Architect the MongoDB-to-SQL-Server migration — design the data access layer transition from MongoDB to DevExpress XPO (SQL), optimize SQL queries to replace Mongo joins, and ensure zero data loss.

· Lead the database rationalization effort — design the analysis and cleanup approach for ~540 unused tables out of ~680, update DevExpress XAF Admin App model, and manage code cleanup of dead table references.

· Drive the Windows Forms to Blazor migration — design the new Blazor architecture, component structure, and state management approach for the tablet application.

· Plan and orchestrate site-wise deployments across 11 global sites with ~1 hour downtime windows per site, including rollback strategies.

AI Workflow Automation Platform

· Design and build the web platform architecture — omnichannel intake (web portal, email, API, bulk upload), SSO integration (SAML 2.0 / OAuth 2.0 / OpenID Connect with Microsoft Entra ID), and responsive UI.

· Architect the SAP S/4HANA integration layer — API abstraction for 13+ document types (PR, PO, GRN, Invoice, Sales Order, Billing, etc.), OData/REST consumption, error handling, and retry logic.

· Design the agentic AI processing layer — integration with OCR/IDP services, AI-driven document understanding, SAP posting orchestration, and autonomous error resolution workflows.

· Implement enterprise-grade security — RBAC with segregation of duties, AES-256 encryption at rest, TLS 1.2/1.3 in transit, tamper-proof audit logging, API security (OAuth 2.0, rate limiting, OWASP protection).

· Design for scale and reliability — support ~500 concurrent users, 5,000 transactions/day, 99.9% uptime, HA/DR (active-active/active-passive), 5x future growth capacity.

· Build the reporting and analytics framework — KPI dashboards (STP%, AI Resolution Rate, First-Time-Right%, workflow TAT), drill-down views by Region/BU/Document Type, SLA-based alerting.

Mentoring & Team Development

· Mentor junior and mid-level developers — guide them on .NET best practices, design patterns, testing, and debugging.

· Conduct technical interviews and contribute to hiring decisions as ATPL scales from 4 to 8+ resources.

· Drive knowledge sharing sessions — document architecture decisions, create technical wikis, and onboard new team members.

· REST API design — API versioning, authentication/authorization (OAuth 2.0, JWT, OpenID Connect), rate limiting, error contracts, Swagger/OpenAPI.

· System design and architecture — layered architecture, microservices vs. monolith trade-offs, event-driven design, CQRS, repository/unit-of-work patterns.

· Git, CI/CD — Azure DevOps or GitHub Actions, automated build/test/deploy pipelines, branching strategies.

· Security implementation — RBAC, SSO (SAML 2.0 / OAuth 2.0 / OpenID Connect), encryption (AES-256, TLS), OWASP Top 10 mitigation, secure coding practices.

Technical Skills — Strong Plus

· DevExpress XPO / XAF — ORM and admin app framework experience (used extensively in manufacturing execution platform).

· Akka.NET — actor model concurrency, message-driven systems, cluster configuration.
