Tech Lead, Platform Stack (Full Stack)

Tech Lead, Platform Stack (Full Stack) E Sentry

Role Purpose

The Tech Lead (Platform Stack) is the technical and delivery leader for the E Sentry Software Team: Platform Stack. In this role, you will be the team lead for a squad of 8+ engineers, owning technical direction, engineering standards, and execution across the platforms backend services, frontend applications, and supporting cloud infrastructureensuring secure, performant, tenant-aware delivery for assets, sensors, work orders, notifications, real-time dashboards, and AI-driven workflows.

You will lead day-to-day technical decision-making, drive architecture alignment through ADRs, coach and mentor the team, and partner with product, QA, IoT, and data teams to ship predictable releases and maintain enterprise-grade reliability.

What Youll Own

1) Technical Leadership and Team Leadership (8+ Engineers)

• Act as the

  hands-on technical leader and delivery owner

  for a team of

  8+ engineers

  (backend, frontend, and full stack).
• Provide

  technical direction

  , unblock delivery, and drive consistent engineering execution (planning build test release).
• Run and elevate team rituals and practices:
• Sprint planning support, grooming, estimation calibration, dependency/risk management
• Clear Definition of Done, coding standards, and review discipline
• Engineering quality gates (testing, security checks, release readiness)
• Coach and mentor engineers:
• Pairing, design reviews, code reviews, and structured feedback to accelerate growth
• Promote best practices across the stack (backend architecture, Angular patterns, cloud readiness)
• Support team health and scalability:
• Capacity planning, work allocation, onboarding guidance, and knowledge sharing
• Contribute to hiring and interview loops as needed (role leveling, technical assessments)

2) Platform Architecture and Multi-Tenancy

• Own and evolve

  tenant-aware SaaS architecture

  using ABP / ASP.NET Zero patterns:
• Tenant isolation, role-based access control (RBAC), data partitioning
• Repository/unit-of-work patterns, caching strategies, and transactional integrity
• Define and enforce service boundaries for core domains:
• assets, sensors, work orders, notifications, and AI workflows
• Lead decomposition/migration strategy from .NET services to

  Python microservices

  :
• Sequencing, contracts, compatibility, rollout strategy, and observability parity

3) Backend Engineering (Primary)

• Design and implement backend services in

  ASP.NET Core

  (ABP & ASP.NET Zero modules),

  Entity Framework Core

  , and

  SQL Server / Aurora

  .
• Build and evolve APIs:
• REST endpoints and

  SignalR hubs

• Tenant-isolated authorization, validation, error handling, and rate limiting
• Implement background processing patterns using:

• Hangfire

  for jobs and workflow orchestration

• Redis

  for caching/throttling and resilience patterns where applicable
• Integrate platform services with:

• Stripe

  and

  Firebase

• Health checks and correlation-aware logging via log4net + middleware
• Integrate and optimize data sources:
• SQL (schema design, indexing, tuning)

• InfluxDB

  for time-series telemetry and data-heavy dashboard performance

4) Frontend Engineering (Secondary, but Accountable)

• Ensure the team builds clean, testable

  Angular 18+

  UIs using:
• Standalone components, TypeScript 5.5, RxJS 7.4
• PrimeNG, Angular Material, ngx-charts
• Define patterns for:
• Reusable components and maintainable UI architecture
• Performance for large datasets (pagination, caching, change detection, virtualization where needed)

5) Cloud, DevOps, and Reliability

• Guide implementation and evolution of AWS-hosted platform components:

• ECS

  for container orchestration

• RDS (Aurora)

  for relational persistence

• S3

  for storage,

  Lambda

  for serverless utilities
• Drive environment consistency and Infrastructure as Code using

  AWS CDK

  and containerized services.
• Contribute to CI/CD and release quality:
• GitHub Actions pipelines, automated testing, versioning and deployment hygiene
• Establish baseline observability and operational readiness:
• Health checks, structured/correlated logging, performance profiling
• Support incident response and post-incident improvements

Key Responsibilities (Day-to-Day)

• Lead technical design and implementation of platform features across backend and frontend.
• Own delivery outcomes for the Platform Stack team of

  8+ engineers

  : planning, sequencing, and release readiness.
• Own code quality: code reviews, testing strategy, maintainability standards, and refactoring priorities.
• Maintain tenant isolation and RBAC correctness across APIs and data access paths.
• Drive .NET-to-Python microservices migration with stable contracts and incremental rollout.
• Partner with IoT and data teams to expose sensor telemetry, alerts, analytics, and reporting.
• Ensure platform stability via rate limiting, background processing, caching, and observability.
• Participate in grooming, ADR creation, and cross-team planning.

Required Qualifications

• 7+ years

  professional experience building web applications, with demonstrated leadership responsibility for delivery and technical direction (formal or informal lead).
• Experience leading or coordinating a team;

  experience leading larger squads (e.g., 610+) is strongly preferred

  .
• Bachelor’s degree in CS/IT or equivalent practical experience.
• Strong backend expertise:

• ASP.NET Core

  Web APIs, EF Core, LINQ
• Multi-tenant modeling, repositories, unit of work, caching strategies
• Strong data skills:
• SQL schema design, indexing, query tuning (SQL Server/Aurora)
• Time-series/streaming integration experience (InfluxDB preferred)
