Senior Software Engineer

Role Description

Amtech is seeking a Senior Software Engineer to lead technical improvements across multiple modules and teams on a portal built for label and flexible packaging converters to make order intake efficient, intelligent, and collaborative for service representatives, distributors, and customers.

Key Responsibilities

• Own projects or major features at the team level, including architecture, delivery strategy, team coordination, and measurable business outcomes.
• Lead technical standards for database changes, code review, testing, logging, and incident response across multiple modules.
• Guide architectural decisions that balance immediate delivery against long-term maintainability, deployment risk, and team capability.
• Lead production incidents involving financial, inventory, or shipping data—determining root cause, safe recovery, and preventive actions.
• Design incremental modernization strategies for complex legacy systems, prioritizing high-impact, bounded improvements over full rewrites.
• Establish database governance including change standards, schema compatibility, multi-customer testing, and safe migration procedures.
• Mentor and train developers in both technical skills (SQL Server, transaction design) and professional judgment (prioritization, risk assessment, incident response).
• Conduct thorough code reviews of changes to critical systems, focusing on business correctness, transaction safety, concurrency, and testability.
• Diagnose systemic issues (frequent defects, slow deployments, onboarding challenges) and propose solutions that improve team effectiveness.
• Communicate across boundaries with product, QA, customer success, and business leadership to understand priorities and constraints.

Required Qualifications

• Senior PHP Knowledge (The Core Engine)
• Senior ReactJS Knowledge (The Front-End Interface)
• AWS Cloud Knowledge (The Infrastructure Layer)
• Expert C# architecture and patterns
• Expert SQL Server and database governance
• Testing and quality standards
• Production systems and incident response
• Modernization and architecture
• Technical Leadership & Soft Skills

Preferred Qualifications

• Experience building or leading large production systems serving millions of transactions or thousands of concurrent users.
• Deep familiarity with at least one complex enterprise system (ERP, financial platform, or high-volume transaction processing).
• Production incident response experience; familiarity with post-mortems and blameless investigation.
• Experience designing systems for multi-tenant or multi-customer deployments with schema and configuration variation.
• Leadership of database migrations on large production tables; understanding of zero-downtime deployment strategies.
• Mentoring multiple junior and mid-level engineers; demonstrated impact on their growth and career progression.
• Experience setting or improving engineering practices: code review, testing, deployment, incident response.
• Speaking, writing, or community contributions demonstrating communication of technical concepts.

Work Environment & Culture

• Mature codebase: 5000+ files, 500K lines of code. You will own critical paths and improve legacy systems.
• Production accountability: Your decisions impact financial records, inventory accuracy, and customer success. Rigorous thinking and risk assessment are paramount.
• Technical leadership: Architecture and standards are set collaboratively with other senior engineers and leadership.
• Multi-team impact: Your standards, mentoring, and decisions affect how multiple teams deliver.
• Continuous learning: Large systems always have surprises; growth mindset and intellectual curiosity are essential.
• Autonomy with guidance: You make most decisions independently but collaborate on major architectural changes.

Growth Path

Within 2–3 years, a successful Senior Software Engineer will:

• Own 2–3 major projects or features that have measurable business impact and demonstrate your strategic thinking.
• Mentor 3–5 developers through significant technical challenges; demonstrate positive impact on their growth, retention, and confidence.
• Establish 2–3 standards or practices (database governance, testing approach, incident response, code review) that are adopted by teams.
• Lead 2+ production incidents or complex investigations; document findings and implement preventive actions.
• Guide 1–2 incremental modernization initiatives with a clear phased strategy and measurable improvements.
• Contribute to hiring and culture-building; interview candidates and provide technical feedback.

Beyond Senior Engineer, growth leads to Staff Engineer, Principal Engineer, Engineering Manager, or Technical Fellow roles—each with different specialization but increased organizational influence.
