We work in Scaled Agile Framework (SAFe), and our development is built on the React ecosystem. Who we are looking for? The company is seeking an experienced Staff Software Engineer to lead the PHP Chapter. In this role, the individual will shape the technical direction and engineering culture across all PHP teams, acting as the central authority on craftsmanship, technical excellence, and professional growth within the discipline. The Chapter Lead will define quality standards, assessment frameworks, and recruitment procedures for PHP engineers across the organization. They will drive strategic initiatives that benefit the entire chapter — shared tooling, engineering practices, and enablement programs — designed to scale across teams and divisions. This role is key in elevating the PHP discipline at organizational scale, fostering innovation and a strong community of practice. Key responsibilities: ​ Standards & Engineering Excellence: Define, codify, and evolve PHP coding standards, architectural guidelines, and quality criteria that apply across all PHP teams. Translate engineering excellence from individual judgment into shared, documented, and (where possible) machine-enforceable rules, especially through adoption of AI-ready documents, skills and similar solutions. Strategic Initiatives: Identify, prioritize, and drive cross-cutting initiatives that elevate the entire chapter — shared libraries, frameworks, tooling, AI-assisted development workflows, observability practices, and modernization efforts. Operate with leverage in mind: prefer interventions that scale across dozens of engineers over one-off fixes. Assessment & Career Development: Own the PHP competency framework and define what "good" looks like at each seniority level. Design assessment, calibration, and feedback processes that work consistently across teams and divisions, replacing ad-hoc evaluation with repeatable structure. Recruitment & Hiring Standards: Define interview formats, technical evaluation criteria, and hiring bar for PHP roles across the organization. Train and calibrate interviewers to ensure consistent, fair, and high-quality hiring decisions at scale. Community of Practice: Build and sustain a strong PHP community across teams — through chapter meetings, knowledge-sharing formats, internal talks, and structured programs. Foster horizontal collaboration so that expertise compounds across the chapter rather than being trapped in individual teams. Governance & Decision-Making: Establish lightweight governance structures (councils, ADR processes, review boards) that enable consistent technical decisions across teams without becoming bottlenecks. Facilitate alignment on contested topics and document decisions for organizational memory. Cross-Functional Influence: Partner with engineering managers, architects, product leadership, and other Chapter Leads to align PHP technical strategy with broader organizational goals. Represent the PHP discipline in cross-divisional forums and contribute to enterprise-wide technical direction. Hands-On Credibility: Maintain enough hands-on involvement — through prototypes, contributions to shared libraries, technical reviews of critical designs, and selective deep-dives — to retain credibility, stay current, and make informed decisions. The role is not primarily a coding role, but technical authority cannot be fully delegated. Enablement Over Tutoring: Scale impact through programs, documentation, internal courses, workshops, and self-serve resources rather than 1:1 mentoring. Where direct mentoring happens, focus it on senior engineers and emerging leaders who will themselves multiply impact across their teams. Travel: Occasionally travel between company offices across different locations to engage with PHP teams in person, participate in chapter events and workshops, and strengthen relationships with engineers, managers, and stakeholders across divisions. Requirements: Bachelor’s or Master’s degree in computer science, software engineering or a related field, or equivalent work experience, At least 10 years of experience in software development with a focus on PHP, Deep understanding of PHP language specifications and experience in developing and maintaining complex backend systems, Proven experience in defining coding standards, security guidelines and best practices for PHP, Excellent skills in conducting code reviews and providing constructive feedback, Experience in training and mentoring developers to improve their skills and knowledge, Strong problem solving skills and the ability to tackle complex technical challenges, Team player and good communication skills to work effectively with other teams and solve conflicts, Self-motivated and able to work independently, in a goal-oriented manner without supervision, Good understand of AI tools in a day to day usage. Nice to have: Experience with legacy systems modernization, Open Source Contributions or Public Speaking. What do we offer: ​ Workplace safety and comfort: Employment based on an employment contract or B2B, Full support during the onboarding period under the supervision of an engaging leader/buddy. Business agency and agility: Real influence on business decisions, the ability to take initiatives and implement your ideas.

About the role: We're looking for a Senior Engineering Manager to lead six engineering teams within a single Agile Release Train (ART). Your closest collaborators will be the technical leaders running each team - developing their skills, removing blockers, and holding them accountable is the core of what you do. You'll work closely with Engineering Leaders, Product Owners and Agile Coaches. You are responsible for making sure they work well together and that the engineering perspective has a strong voice at the table. In practice: Roughly 50 % of your time is spent on leadership: building team capability, handling performance situations, running recruitment, and shaping the culture of the cluster. Around 40% is business-focused - PI planning, tracking progress against objectives, mentoring leaders, and reporting status and risks to the Director of Engineering. The remaining slice is technical: no coding required, but you'll need enough judgment to evaluate trade-offs, oversee architectural decisions, and credibly represent engineering in strategic conversations. The environment is complex - 289 microservices, a diverse tech stack, and a scale where cross-team dependencies directly impact delivery. You don't need to be an expert in everything, but you do need to bring structure, clarity, and ownership to a domain where things move fast.
