Modern enterprise software architecture requires more than just clean code and functional microservices; it demands deep alignment with industry-standard frameworks, rigorous governance, and robust domain-driven design. For seasoned software architects and technical leaders based in Colombo, the Senior Tech Lead – Software Engineering position at Axonect offers a high-impact opportunity to shape enterprise-grade financial and telecommunication systems.
This role sits at the intersection of technical oversight, banking architecture standards, and team mentorship. This guide examines the core expectations, mandatory frameworks like BIAN, technical competencies, and person specifications required to succeed in this onsite contracting role.
Company Positioning and Role Context
Axonect operates within a competitive ecosystem where technical excellence directly influences core business operations. This specific requirement is structured as a full-time onsite role based in Colombo. As a contracting opportunity spanning a 06-month vendor submission window, the position demands an immediate, hands-on leader capable of stepping into active development cycles, managing stakeholder expectations, and enforcing enterprise architecture standards from day one.
Core Responsibilities and Technical Leadership
The primary mandate of the Senior Tech Lead is to bridge high-level enterprise requirements with practical software implementation. Day-to-day duties are distributed across several critical pillars:
- Technical Leadership & SDLC Oversight: Provide strong technical guidance throughout the Software Development Life Cycle (SDLC). This includes participating in requirement gathering, Architecture Review Board (ARB) discussions, peer code reviews, deployment activities, and production support.
- Solution Architecture & Domain-Driven Design (DDD): Enforce coding standards, security requirements, and scalable application designs. Leaders must promote modular software development, reusable design patterns, and rigorous Domain-Driven Design principles.
- API Governance & Design-First Approach: Drive Design-First API development using OpenAPI/Swagger. Responsibilities include defining strict request/response contracts, establishing versioning strategies, and implementing standardized error-handling mechanisms that align with enterprise integration standards.
- Performance, Reliability, and Observability: Design solutions that satisfy Non-Functional Requirements (NFRs) such as performance, high availability, scalability, reliability, and security. Monitoring and logging must be maintained using the ELK Stack or equivalent observability tools.
- Cryptography & Secure Communication: Apply fundamental cryptographic principles, including symmetric, asymmetric, and hybrid encryption models, to guarantee secure communication across enterprise systems and APIs.
The Mandate for BIAN Standards and Banking Integration
A distinctive feature of this role is its strict adherence to the Banking Industry Architecture Network (BIAN) standards. Candidates are not merely expected to have heard of BIAN; the specification lists BIAN Standards & Banking Service Design as mandatory.
Key requirements under this domain include:
- Ensuring architectural alignment with BIAN reference architecture and service domains.
- Designing standardized banking services, APIs, and microservices boundaries that integrate smoothly with core banking systems.
- Promoting enterprise API governance to prevent architectural drift across multi-team deliverables.
Technical Competencies and Stack Requirements
A successful candidate must possess deep expertise in Java and enterprise software engineering principles. The technical evaluation focuses heavily on the following areas:
- Java & Core Concepts: Mastery of Object-Oriented Programming (OOP), Java data types, string immutability, heap memory management, memory leak analysis and prevention, exception handling, and custom annotations.
- Design Patterns & Code Quality: Practical application of creational, structural, and behavioral design patterns (such as Singleton, Factory, Builder, and Strategy) alongside code quality analysis using tools like SonarQube.
- Data Management & ORM: Solid understanding of relational databases, SQL optimization, and ORM frameworks (Hibernate, Sequelize, SQLAlchemy) alongside familiarity with NoSQL stores, caching mechanisms, and message brokers.
- DevSecOps & Testing: Active participation in unit testing, API testing, performance testing, CI/CD pipeline execution, peer reviews, and production incident troubleshooting.
Candidate Qualifications and Person Specifications
Because this is a senior leadership position, the qualification criteria reflect a high bar for professional maturity and technical tenure:
- Educational Foundation: A Bachelor’s degree in Computer Science, Software Engineering, Information Technology, or a closely related discipline.
- Professional Experience: A minimum of 8+ years of experience in software engineering, with verified history in a technical leadership capacity guiding enterprise application development teams.
- Domain Knowledge: Strong experience designing enterprise applications, APIs, and microservices. Experience within banking and financial services technology is considered highly desirable.
- Soft Skills: Excellent stakeholder management, technical communication, mentoring capabilities, and cross-functional problem-solving skills.
Application Strategy
If you meet these technical thresholds and possess hands-on expertise with BIAN architecture and enterprise Java systems, you can apply directly through the professional network listing on LinkedIn. Ensure your resume highlights quantifiable achievements in system performance optimization, microservices migration, and enterprise API governance before submitting your vendor application.
