Director of Software Engineering (Poland)

At Flosum, we are building the world's best software for the modern enterprise. Our team is passionate about crafting elegant, high-performance products that delight our customers and set a new bar for engineering excellence. We combine deep expertise in cloud-native development with a relentless focus on quality, speed, and innovation. Every line of code we ship is built to scale, built to last, and built to make a real difference for the businesses that rely on us.

We are a company where technologists lead, ideas win on merit, and shipping great software fast is a core value-not a slogan. If you believe world-class engineering teams are the ones that move quickly and build things right, you'll feel at home here.

About the Role

We are hiring a Director of Software Development to lead a team of 10 engineers building and scaling our Node.js and Salesforce-integrated products. This is a hands-on leadership role for a technical architect at heart who can compress delivery schedules, drive developer velocity, and own the performance of the overall solution. You will be the single point of accountability for turning our roadmap into shipped software-on time, at quality, and at scale.

What You'll Own

• Lead, coach, and grow a team of 10 full-stack developers across Node.js services and Salesforce customizations.
• Drive measurable improvements in developer velocity using DORA metrics: lead time, deployment frequency, change failure rate, and MTTR.
• Compress delivery schedules by breaking epics into small, independently shippable slices and challenging inflated estimates with data.
• Architect end-to-end solutions spanning Node.js microservices, APIs, event-driven patterns, and Salesforce (Apex, Lightning, integrations).
• Own solution performance: latency, throughput, scalability, and cost-set SLOs and hold the team accountable to them.
• Establish estimation, sprint, and release discipline; remove blockers; enforce accountability without burning the team out.
• Partner with Product, QA, and Infrastructure to align roadmap, capacity, and dependencies.
• Recruit, onboard, and performance-manage engineers; build a culture of ownership and speed.

Requirements

• 10+ years in software engineering with 5+ years leading development teams of 8-20 engineers.
• Deep, current hands-on experience with Node.js (Express/Nest, async patterns, performance tuning, microservices).
• Working knowledge of the Salesforce platform-Apex, Lightning Web Components, Flows, REST/Platform Events, and Node.js Salesforce integration patterns.
• Proven technical architect background: designed distributed systems, API contracts, data models, and performance-critical solutions in production.
• Track record of schedule compression-case studies where you measurably reduced cycle time or pulled in release dates without sacrificing quality.
• Strong estimation and planning discipline in Agile/Scrum or Kanban environments.
• Experience driving solution performance: profiling, caching, query optimization, horizontal scaling, and observability (APM, logs, traces).
• Cloud-native delivery experience (AWS preferred) with CI/CD, IaC, and modern DevOps practices.
• Excellent stakeholder communication-can negotiate scope vs. time vs. quality with executives.

Success Metrics (First 6-12 Months)

• Reduce average lead time for changes and increase deployment frequency to meet DORA "high" or "elite" benchmarks.
• Ship the current roadmap on a compressed timeline agreed with leadership.
• Improve estimate accuracy (commit vs. deliver) to within an agreed tolerance.
• Meet or exceed performance SLOs for the Node.js + Salesforce solution stack.
• Retain and level-up the existing team while filling any skill gaps.

Why Flosum

At Flosum, we believe great software is built by great teams-and great teams are built by leaders who care deeply about both the craft and the people. You will have the autonomy, the talent, and the mandate to build something exceptional. If you want to lead a team that is setting the standard for what world-class software looks like, we want to talk to you.
