Sverige, Sweden Mozaiq Full time

Role Overview

As a Senior Front End Software Engineer, you will own frontend solutions end-to-end — from defining problems aligned to OKRs, through design, build, launch, and ongoing operation. The role combines hands-on technical leadership with strong collaboration across product, engineering, and business teams.

You will design and build customer-facing features as well as internal platforms that improve engineering efficiency. This role requires comfort with ambiguity, strong decision-making, and a focus on delivering measurable customer and business value.

Key Responsibilities

  • Own frontend products end-to-end: problem definition, architecture, delivery, and operations
  • Deliver customer value while balancing speed, scope, and priorities
  • Act as a technical leader and go-to partner for Product Management
  • Architect scalable frontend frameworks leveraged across teams
  • Identify key technical risks and opportunities early
  • Lead large-scale scoping, estimation, and planning efforts
  • Invest in long-term technical health ("tech wealth") to accelerate shipping
  • Use data to form hypotheses, iterate quickly, and drive impact
  • Mentor engineers, give and receive candid feedback, and raise engineering standards
  • Lead complex engineering discussions and present options to leadership
  • Step in for development management duties when required

Required Experience & Skills

  • 8+ years of software development experience building production web applications
  • Strong experience with React, Vue, Angular, or similar frameworks
  • Deep expertise in JavaScript and TypeScript, CSS, , and modern tooling (NPM, Yarn, Babel, Jest, Cypress, Enzyme)
  • Mastery of REST and GraphQL APIs, including influencing API design
  • Strong understanding of SSR, CSR, and static generation tradeoffs
  • Solid grasp of software architecture, data structures, caching, and async programming
  • Proven experience leading large, multi-team projects from concept to post-launch
  • Comfortable working on under-defined problems and less glamorous but high-impact work
  • Experience mentoring engineers and building strong engineering teams
  • Ability to communicate clearly with both technical and non-technical stakeholders
  • Strong partnership skills with Product Management
  • Experience identifying project risks, evaluating build vs. buy decisions, and tailoring technical solutions to business needs
  • Familiarity with analytics and data tools such as SQL, pandas, and FullStory

Mindset & Ways of Working

  • Outcome-focused and customer-driven
  • Constructively dissatisfied with the status quo
  • Comfortable making tough tradeoffs
  • Focused on what's right, not who
  • Collaborative, curious, and continuously improving
