Designation: Scala Tech Champion / Principal Back-End Engineer

Location: Bangalore

Experience: 10 to 18 Years

We are seeking an accomplished Scala Tech Champion with 10+ years of software engineering experience to provide technical leadership within a cross-functional product team responsible for a customer-facing platform.

In this role, you will lead the design and evolution of scalable, highly available back-end services in a cloud-native, event-driven environment. You will act as a recognized authority on Scala engineering, distributed systems, and software architecture—setting technical direction, establishing engineering standards, mentoring colleagues, and solving complex challenges across teams.

The position requires strong autonomy, deep architectural expertise, pragmatic decision-making, and close collaboration with Product, Front-End, Platform, and SRE teams.

What will you do

Define and champion the technical vision for Scala-based back-end services and platforms.
Architect, develop, and evolve scalable, resilient, and highly available distributed systems.
Establish and promote Scala engineering standards, patterns, and development best practices.
Write clean, maintainable, testable, and high-performance code, primarily using Scala.
Lead architectural decisions involving microservices, event-driven systems, data consistency, and service integration.
Guide the application of functional programming principles using technologies such as Cats and Cats Effect.
Drive the effective use of Pekko/Akka, Kafka, Event Sourcing, CQRS, and Domain-Driven Design.
Identify and address architectural risks, performance bottlenecks, scalability constraints, and technical debt.
Collaborate with Product and other engineering disciplines to translate business needs into pragmatic, user-centric technical solutions.
Mentor engineers through technical coaching, pair programming, design discussions, and constructive code reviews.
Facilitate architecture reviews and technical knowledge-sharing sessions across teams.
Define and uphold standards for code quality, security, reliability, observability, and performance.
Improve CI/CD pipelines, engineering workflows, and delivery practices.
Partner with SRE and Platform teams to improve operational readiness, fault tolerance, and production resilience.
Evaluate emerging technologies and guide their adoption when they deliver clear business or engineering value.

Required knowledge and experience

10+ years of professional software engineering experience, with substantial experience designing and delivering complex back-end systems.
Deep expertise in Scala and its ecosystem, including Pekko/Akka, Cats, and Cats Effect.
Strong understanding of functional programming concepts and their practical application in production systems.
Proven experience acting as a technical lead, principal engineer, architect, or technology champion.
Strong Java knowledge; Python experience is an advantage.
Extensive practical experience with Event Sourcing, CQRS, and Domain-Driven Design.
Proven ability to design, evolve, and scale distributed microservice architectures.
Experience building high-performance, resilient, secure, and observable APIs.
Deep understanding of distributed systems, concurrency, consistency models, fault tolerance, and recovery patterns.
Hands-on experience with Kafka and event-driven architecture at scale.
Strong cloud-native development experience on AWS.
Advanced experience with Docker, Kubernetes, and modern deployment practices.
Experience with relational and non-relational databases, including data-modeling and performance considerations.
Strong understanding of observability practices, including metrics, logging, tracing, alerting, and production diagnostics.
Experience improving CI/CD pipelines and automated testing strategies.
Demonstrated success in Agile, cross-functional product-development environments.
Ability to balance long-term architectural goals with pragmatic and incremental delivery.

What will you bring as a colleague

A technology-champion mindset and the ability to inspire engineering excellence across teams.
Strong technical judgment and the confidence to challenge assumptions constructively.
A pragmatic approach that balances technical quality, delivery speed, operational risk, and business value.
A growth mindset and a genuine commitment to developing yourself and those around you.
The ability to mentor engineers and communicate complex technical concepts clearly to both technical and non-technical stakeholders.
A collaborative and inclusive leadership style that builds alignment without relying on formal authority.
Ownership, curiosity, and the determination to improve systems, processes, and engineering culture.
Excellent written and verbal communication skills in English.
