Longevity Partners is seeking a seasoned and visionary Principal Software Engineer to lead the design, coordination, and scaling of digital products central to our consultancy-as-a-service offerings. This individual will be instrumental in driving the architectural, operational, and strategic roadmap for the firm's tech stack -- particularly the Impact Service Platform (ISP) and related AWS-hosted platforms.
This is a hands-on leadership role with significant influence across DevOps, architecture design, database integration, team management, and product direction. You will coordinate a rapidly growing engineering team and play a pivotal role in enabling scalable, high-performance solutions that support our sustainability consultancy mission.

Key Responsibilities:

DevOps & Cloud Infrastructure

Lead and manage DevOps operations across AWS services, including Amplify, EC2, Lambda, and S3. Own CI/CD strategy and implementation, ensuring robust automation and deployment pipelines. Oversee and refine ETL processes to support real-time and batch data flows between internal platforms and client-facing services.

System Architecture & Engineering Leadership

Define and own system architecture strategy, ensuring resilience, scalability, and security across multiple applications. Ensure platform modularity and service orchestration using modern best practices in microservices, serverless frameworks, and containerization.

Data Engineering & Database Coordination

Design and manage robust integration strategies between relational (SQL) and non-relational (NoSQL, e.g., DynamoDB, MongoDB) databases. Guide platform schema design for ESG data tracking, analytics, and AI/ML readiness.

Product & Strategy Contribution

Collaborate with Product Managers and senior stakeholders to align technical decisions with business goals, especially for the ISP, BIU, and Policy Tracker platforms. Act as a technical advisor on features such as dynamic recommendation tracking, automated report generation, and AI-integrated consulting tools.

Agile Delivery & Scrum Contribution

Champion agile best practices, driving planning and delivery in Jira. Facilitate sprint planning, backlog grooming, and retrospective sessions in coordination with product and design leads.

Team Leadership & People Management

Directly manage and mentor a cross-functional team of 4+ developers with a roadmap to scale. Foster a culture of technical excellence, code quality, and continuous improvement. Guide recruitment and onboarding of additional technical hires.

Proven experience with AWS services (including Lambda, RDS, DynamoDB, EC2, Amplify). Advanced proficiency in backend (Python, Node.js) and frontend (TypeScript, React) technologies. Deep understanding of modern database technologies and data integration patterns. Strong grasp of CI/CD tools and practices (e.g., GitHub Actions, Jenkins, Terraform). Familiarity with containerization (Docker/Kubernetes) and serverless architecture.

Professional Experience

6+ years in software engineering, with a strong track record in technical leadership and architecture. Experience managing cross-functional teams in agile environments. Background in SaaS platform development; sustainability or ESG software domain is a plus.
