As Senior Software Engineer you will be a key contributor to designing, building, and operating scalable services within a distributed, integration-heavy platform, while also guiding other engineers through code reviews, technical decisions, and delivery standards.

We are looking for a candidate with strong JavaScript expertise who will act as a technical leader for one of our core platform teams. This role combines hands-on engineering with technical leadership, system ownership, and close collaboration with product, architecture, and external vendors.

This is not a pure people-management role, but you are expected to lead technically and act as a go-to person for your domain.

Drive engineering protocols (code quality, testing, observability, security)

Review designs and code, providing constructive and pragmatic guidance

Mentor mid-level and senior engineers; support junior engineers when needed

Software Engineering

Design, develop, and maintain JavaScript-based backend services (Node.js)

Build scalable, resilient APIs and integration layers

Work with event-driven and asynchronous architectures

Ensure production readiness: monitoring, logging, alerting, and performance tuning

Participate in on-call rotations and support production issues when required

Architecture & Platform Work

Contribute to service architecture, domain boundaries, and API contracts

Work closely with architects and other technical leads on cross-team initiatives

Ensure systems meet non-functional requirements (availability, latency, security)

Support gradual refactoring and modernization of existing services

Collaboration & Delivery

Partner closely with Product Managers and Business Analysts to shape solutions

Coordinate technical dependencies with other teams and external vendors

Support planning, estimation, and risk identification

Translate business requirements into clear technical execution plans

What You will need to be successful:

Many years of professional software engineering experience

Strong proficiency in JavaScript and Node.js

Experience building backend services and APIs in production environments

Solid understanding of distributed systems and service-based architecture

Experience working with cloud platforms (AWS preferred)

Strong knowledge of REST APIs, authentication/authorization, and data modeling

Experience with CI/CD pipelines, automated testing, and code-quality tools

Proven ability to lead technically within a team or project

Previous experience as a Technical Lead, Team Lead, or Senior Engineer with ownership responsibilities

Comfortable making decisions with incomplete information

Able to balance delivery pressure with long-term maintainability

Desirable Criteria:

Experience with event streaming (e.g., Kafka, SNS/SQS, EventBridge)

Familiarity with microservices and serverless architecture

Experience in integration-heavy platforms

Exposure to vendor-led or outsourced development models

Knowledge of TypeScript

Experience operating services on a scale (multi-region, multi-market systems)
