Sr. PHP

What does day-to-day look like:

• Design algorithmically rich coding problems and systems that challenge reasoning, planning, and correctness in real-world software scenarios.
• Develop high-quality software solutions and comprehensive test suites, ensuring code robustness, correctness, and coverage across edge cases.
• Craft clear, unambiguous technical specifications and problem statements, balancing creativity and engineering precision.
• Ensure thorough coverage across algorithmic and systems domains, including classical data structures, performance engineering, mathematical logic, and constraint-based design.
• Apply structured metadata and documentation to development tasks, capturing taxonomy, difficulty, domain relevance, and reliability metrics.
• Participate in peer reviews and quality assurance processes to uphold rigorous engineering standards and system consistency.
• Deliver work in a maintainable, modular, and scalable format ready for production integration or downstream application use.

Requirements:

• 5+ years of experience in software engineering, algorithm design, or systems-level programming.
• Strong proficiency in PHP with at least 4+ years of experience
• Proven ability to write clear, concise, and technically challenging algorithmic code.
• Strong understanding of algorithmic complexity, performance optimization, and computational constraints.
• Experience with test automation, benchmark creation, or complex systems evaluation is a strong plus.
• Familiarity with modern software data formats (e.g., JSON, YAML) and version-controlled codebases.
• Domains of Expertise: Successful candidates will demonstrate deep fluency in at least four of the following areas:
• Core Data Structures: Trie, Segment Tree, Union Find
• Algorithmic Paradigms: Dynamic Programming, Greedy Algorithms, Bitmasking
• Graph Algorithms: Shortest Paths, Network Flow, Topological Sorting
• Mathematics & Number Theory: Geometry, Probability, Modular Arithmetic
• String Processing: Suffix Trees, Rolling Hashing, Pattern Matching
