Software Engineer II
Location: Dallas, TX (On-site: 5 days in office)
The Firm:
Data Driven and Real-Asset Focused

Stronghold Investment Management (“Stronghold,” “SIM,” or “the Firm”) is a technology-driven, vertically integrated investment manager focused on real-assets and related private markets. Stronghold seeks to deliver best-in-class risk-adjusted returns through an investment framework that features comparatively rapid transaction velocity, deep technical expertise, creative financial structuring, and objective and algorithmic decision making.

Stronghold was founded by Ryan Turner in 2016 and has deployed over $1.6 billion in capital across 10+ investment vehicles. Ultimately, Stronghold intends to apply its technology-intensive investment approach to a variety of specialist real assets verticals, including:

• Oil & Gas
• Renewables
• Telecommunications and Technology Infrastructure
• Billboards and Fixtures
• Mining & other commodities
• Utilities

Your Mission
We're seeking a Software Engineer II to join Stronghold's Tech Development team, where your backend and data systems work directly powers a technology-driven investment firm moving billions of dollars across real assets globally.

This isn't a typical engineering role. You'll build the scalable, high-performance infrastructure that gives Stronghold's edge: fast transaction velocity, algorithmic decision-making, and data systems that no traditional investment firm has. Working primarily within a Ruby on Rails ecosystem, you'll help develop and scale backend services powered by technologies including PostgreSQL, Kafka, Elasticsearch, Redis, and Microsoft Azure
.

You'll work alongside senior engineers and cross-functional teams to shape architecture, drive performance, and own meaningful pieces of a stack that's genuinely differentiated in private markets.

This is a rare opportunity for a software engineer with 3–6 years of experience who's ready to go beyond feature work, someone who wants their technical decisions to matter, their contributions to be visible, and their career to accelerate inside a firm that moves fast, thinks deeply, and invests in its people.

Key Responsibilities –
What You’ll Own

• Build the backbone. Design, develop, test, and maintain the APIs, backend services, and data workflows that power firm-wide operations, from transaction processing to investment analytics, primarily within a Ruby on Rails environment.
• Scale what matters. Architect and optimize data-intensive applications for performance, reliability, and efficiency, because at Stronghold, speed and accuracy aren't nice-to-haves, they're the business.
• Shape the platform. Collaborate with senior engineers, product teams, front-end developers, and other cross-functional stakeholders on system architecture and long-term technical design, contributing to decisions that will define how the firm operates for years.
• Own the pipeline. Build and maintain automated and event-driven data processing pipelines using technologies such as Kafka to keep information accurate, consistent, and moving, the kind of infrastructure the investment team depends on daily.
• Write code that lasts. Deliver clean, testable, maintainable code with a strong point of view on scalability, and back it up through thoughtful code reviews, testing, and CI/CD practices.
• Make the database fast. Optimize queries, data models, indexing strategies, and schema designs across technologies including PostgreSQL, Redis, and Elasticsearch so nothing slows down the people making decisions with this data.
• Build for the cloud. Develop and support backend applications and services in Microsoft Azure, contributing to scalable cloud architecture and modern deployment practices.
• Keep the…
